And what about a project like regex, which *has* the eyeballs on PyPI,
but the core devs aren't confident enough of its maintainability yet
to be happy about adding it directly to the stdlib with full backwards
compatibility guarantees? The easy answer for us in that context is to
just not add it (i.e. the status quo), which isn't a healthy outcome
for the overall language ecosystem.
Really, regex is the *reason* this PEP exists: we *know* we need to
either replace or seriously enhance "re" (since its Unicode handling
isn't up to scratch), but we're only *pretty sure* adding "regex" to
the stdlib is the right answer. Adding "__preview__.regex" instead
gives us a chance to back out if we uncover serious problems (e.g.
with the cross-platform support).
