The Internet being the Internet, sha-1 hashes will trickle in forever.
I'd rather have the diagnostic say "obsolete hash" than "syntax
error."

If you look at this curdle draft that deprecates RC4, it goes through
and makes changes to turn OPTIONAL to MUST NOT and the like, but it
doesn't try to undefine the obsolete rc4 crypto modes.  I think you'll
find that typical in crypto updates.
