Earlier feedback would have been had if there had been
some announcement of the proposed considerable changes
on the ietf-822 mailing list, or via an IETF WG

Entirely appropriate.  And the proposed draft would
invalidate the meaning of the valid RFC 3066 language
tag "sr-CS", which is currently in use.

If it makes you happy, you can exclude private-use
tags from an explicit limit.
