The proposed patch would result in a warning about every collation-
sensitive index during every macOS major version upgrade, ie about
once a year for most people.  Seeing that Apple only actually touch
their POSIX collations once a decade or so, that's way too far over
on the crying-wolf end of the scale for me.  We need something that
has at least *some* connection to actual changes.
