The big difference is that labels are not an identifier.  At all.  In
any way.  No, not even a little bit.

It's flaky, slow, and a glob of messy code where one line would do and
be better in every way (since the whole thing is fundamentally designed
to look up things by URI).

Yes.

This is only true for presets saved by Jalv, but even then is only true
if the name happens to be restricted so it's not changed to make a
suitable directory name.

It's not true in general, and many if not most factory presets do not
follow that simplified structure, which only exists to make saving them
less of a nuisance.
