This shows that it's very important to avoid the situation where there
exist implementations of insufficiently mature specifications: once
those implementations are out there, the protocols must virtually
forever support them.
This is of course not compatible with "let's ship a 80% workable spec
and hammer out what's missing in the next version" thinking that is
not uncommon in the IETF.
