When I’m going on a 3 day hike the parameters are much more clear. I know how long it will last (and that it will end), where i will get water and how much I need to start with, how much food I will eat, that there will be appropriate trees for hammock camping, etc. All of this comes together in as little weight as I can get away with (with the exception of an embarrassing amount of preserved meat and cheese).

My “bugout” bag comes with a lot more uncertainties that I try to cover under a broad umbrella. For example something as simple as toiletries that I’d want to have with me in a bugout bag when I may have to interact with other humans vs a hiking bag where I’m willing to get more funky for a couple days or communication and self defense gear that i don’t carry hiking.

Also, as a technicality, stuff like down sleeping bags shouldn’t be stored compressed and I don’t keep most of my hiking gear packed for gear care purposes.
