For passing data from client to server, there's no particular reason not
to use the binary format for any data type that you understand (and
where you're passing the data type oid explicitly in the query, rather
than just leaving it as unknown).
For results, things are harder, because libpq is currently
all-or-nothing about result type formats, and if you start using
extension types then not all of them even _have_ a binary format. And to
decode a binary result you need to know the type, and have code to
handle every specific type's binary format.
