In every one of these threads I learn some new axis of git that JJ doesn't support, so I really do wonder if JJ should have squatted upon a different DVCS given how much it wants to do things the JJ way leading to folks with git experience being sad
nah, git was absolutely the right thing to squat on - its ubiquitous, so making it seamlessly powerful and easy to use makes for easy adoption. If it was built on pijul or whatever, I'd never have given it a try.
to the extent that niche things might not be supported (yet), so be it. It suits the needs of the vast majority of people. Moreover, if you need those things, I BET you can just do it via git and then carry on working in jj, since jj sits on top of git
Ehh these are mostly edge case features that are very important to some, but not relevant to most. I've been using Jujutsu full time with dozens of repos and the only one that's come close to mattering is submodules (which are easy to work around with a colocated repo + `git submodule update`).
CRLF autoconversions especially shouldn't have been supported, imho. Git on Windows's default setup still converts LF to CRLF to this day, even though every program on Windows has understood LF for a number of years.
