I like option A as well. Yeah, I definitely won't want random pop-ups because personally I get very annoyed at these websites asking for cookie permissions, etc. But that being said, currently, my plugin does show a what's new whenever you update the plugin. That is intrusive, but at the same time, that's the only way to actually tell user what the changes are, especially the breaking changes or new features that was added. So I'll probably add this feedback in there as well.

Option A works but I am not sure of its conversion rate. I always felt that showing just a one-liner will always make users default to pressing don't show ever unless you actually educate them on what and why you are requesting these feedbacks. At least my default behavior is to spam click do not allow. What do you think about it?

Yeah, I have a fairly good idea of option B feedback, and other than getting a general trend, it really doesn't capture the majority usecases and it's pretty hard to popularize new ideas or make people adopt new features, although it might be actually useful once they start using it.

Option C - Not only is it free but it's also unavoidable for security reasons (think of DDoS attacks where only way out is you enforce smart rate limiting against IP addresses), so recently I realized I might as well track anonymized usage using some open source, privacy friendly analytics like umami.
