I don't think this will harm our implementations.
The type is still string. The pattern will change but that is handled by a
library.
Whatever pattern is used will get handled the same way.

The same problem exists for 'date' and 'date-no-zone' types,
but they are not used very much.

But...

Since import-without-revision is used most of the time,
a module importing ietf-inet-types will get what?
Very implementation-specific, that's what.
Maybe both versions of ip-address present in the same server, maybe not.
