I stash half-baked work to keep it separate from quality commits. When I come back to the stash, I may or may not like where it was going and decide to build on it.
For some reason it feels ephemeral and I worry that I’ll lose the stashed changes like when you accidentally overwrote the copy/paste clipboard
That said for me the stash is usually used either for temporary stuff (eg taking my current work to another branch) or for things that might be useful to reference later but I will rewrite differently anyways; stuff I want to keep goes into a WIP commit.
I know stash feels easier to a lot of people, and that’s a valid reason, but it’s really no more typing or thinking to use branches instead, it just might require changing habits.
