resorting to normal mpz_class operations only for normal values.

Provided your special values don't reach the mpq functions there shouldn't be any problems.

A few mpq functions will be happy with any values actually, eg. mpq_set and the input/output routines I think.

e.g., if the (present or future) implementation does too much automatic canonicalization.

There's no plans for anything like that.
