Why not something a bit more straightforward. Like:

[C] MODE 977BIS (or READER xxx, or whatever, to describe this rev of 
the spec compliance)

[S] 20x 977bis compliant client acknowledged


Compliant clients would then get 45x codes as expected while clients 
not issuing such a mode command would see the old 48x codes as 
expected.

This also allows compliant clients to more easily negotiate old vs. 
new servers.
