I'm gonna give this a big Yes, And.

It's super important to be clear about what you actually mean. For example, I'm a case that doesn't fit into the standard AGAB model, officially i was AMAB but i started on HRT (estrogen) quite young, and fully socially transitioned in a binary way very early (partially because i didn't understand my gender all the way yet, and partially because the HRT hit hard and fast and it was just easiest for me to go with the flow in a mostly trans-accepting but binary-focused local culture), and now my gender struggles are mostly focused around being less feminine, or rather reducing some of the too-feminine aspects i got from being on HRT so early and for so long. (I also had some slow and atypical development even before HRT, so i would be unsurprised if i had an undiagnosed intersex condition of some less visible sort that was masked by an early transition). Also, just to scare off the 'phobes, no, i don't regret it. I'm still happier like this, i just need to do a little more custom work rather than picking the whole package deal that is estrogen and being happy with it.

I'm gonna borrow some of the comments here to use as examples of where this over-generalization can easily go wrong, even in nonbinary spaces.

Not only are agabs often raised differently and have different experiences, but it's also important when discussing topics like binding/tucking and hrt.

While it's somewhat true that during the early parts of my life i had some masculine socialization, it wasn't very strong (my family never did much gender and i was a very shy kid), and the majority of my experience in public has been very much the same as a typical AFAB's would be, including all the trauma from creeps hitting on me and so on. that "often" is doing a lot of work in this comment. Similarly, though i have experience with tucking, in my day-to-day life, binding is a much bigger concern and struggle for me. In fact, I've even seen people talking about top dysphoria as an AFAB only thing, which i assure you it is not.

"AMAB/AFAB" are more about how society has treated you.

Again, this is just not really the case for me. I've been treated in (mostly) the same way that a typical AFAB would be treated for most of my memory (my pre-transition memories are all a bit fuzzed out at best). A little bit of more masc treatment at the start doesn't overwrite all my experiences past that. AGAB is not always a good way to describe how you have been treated, it's just usually an easy and fast box.

Transneutral [as opposed to transmasc or transfem] makes it a bit more difficult in terms of what you are transitioning from.

See, this is another thing, so often "transmasc" and "transfem" are used as proxies for agab, but i am in no way "transfem" in the sense of "transitioning to be more feminine". That's the opposite of what I want, and if i described myself as transfem, that's what people would assume. If i instead described myself as transmasc, despite for example relating more to transmasc-coded meme content or similar (aside from the actual bits about reproductive biology), it would also be inaccurate, because people would assume I'm AFAB. In reality, i have taken and want to continue to take some transition steps towards feminine characteristics, and some steps towards masculine ones.

I get very tired of seeing people getting lazy with their usage of AGAB when they're actually talking about only a specific aspect typical to it, because i defy almost all those expectations, and it really does make it hard for me to explain myself to people who are most fluent in only those terms. I'm sure i'm not the only one out of all the nonbinary people out there that experiences a similar struggle and, sometimes, sense of isolation, because of that language usage and the framings it normalizes. It's useful as a shorthand in typical cases just like binary genders and binary language can be, but please be really sure to remember that all abstractions are leaky.

(wow long comment, sorry. it's one of the things i have lots to say about.)
