Eh?  The latest version will then proceed to not be the latest anymore.
And most software distros do get upgraded sooner or later.

Right, it should not be default for LDAPv2 (or v1:-)

Definitely non-critical.  Then it should be no problem if third-party
DSAs do not support it, though I must admit I don't know if real-life
implementations live up to that.

If it's not made the default, I wouldn't bother.  It's people who would
rarely fiddle with LDAP controls who would have most use for it.
