Yes...  But eventually I expect that "nightly" features migrate
over to "stable".  And since neither of those are specified in
terms of actual version numbers, it's essentially impossible from
this to decide what the minimum supported rust version is for
this package.

Nosing around a bit in the py-pydantic-core package I find that
its Cargo.toml file has

rust-version = "1.75"

which by today's standard in the rust universe has already
managed to be "old".  Is this the MSRV?  I suppose this means
that any version >= 1.75 will do?

This points back to whoever wrote that README.md entry which
implicitly said "your rust version is (probably) too old, upgrade
to the most recent stable to ensure that it isn't" was lazy and
just pushed the user to needlessly upgrade when it possibly
wasn't needed for this particular package?
