I mean none of the options are great, imo.

- "commit" is overloaded with git, and jj still uses commits for other things under the hood. - "patch id" is overloaded with patch files, and jj still uses git's snapshots, not patches (unlike darcs/pijul, iiuc) - "patch revision id" isn't bad, but it's a bit wordy - "change id" just seems vague, since it's unclear where one change begins and another ends

"revision" at least captures the idea that you are revising the same piece of functionality, but then you might expect each snapshot/commit to be a different revision, and not have the same ID, which also isn't quite right.
