Hm, okay, this is tricky, but alright.

Can you check this #2363 (comment) too?

Actually, I think isSelfAtom only matters when writing an atom (because we should write to the correct atom). For read(sub) purposes, since they are always connected via atom dependency, isSelfAtom does not matter from the correctness perspective (but maybe it could have some performance benefits)?

but maybe it could have some performance benefits

isSelfAtom is not only for jotai-scope, so some kind of "correctness" is important.

This version has two minor improvements for library authors. It's
wonderful to see Jotai ecosystem growing. No major bugs have been
reported lately. It's fairly okay to say the current version is pretty
stable.
