I don't know what would be a good reason to define the opclasses in
separate contrib extensions. I think it's going to be a nuisance to
users, so unless there is some strong argument for it, I'd suggest not
to do it. I found it being discussed here:
https://www.postgresql.org/message-id/CA%2BTgmoajaQKBUx%3DvaTUFo6z80dsRzBw__Nu41Q4t06baZep3Ug%40mail.gmail.com
but there weren't any strong arguments put forward.
It seems a good experiment to have done it, though, since we now know
that there is a limitation in the existing SQL interface. Maybe the fix
to that problem is to add a new clause to CREATE/ALTER OPERATOR CLASS to
let you define what goes into opckeytype. However I don't think it's
this patch's responsibility to fix that problem.
