Yes, I agree, but we might also move the traits class to some other
location so that it could be used by more than just convn.  It seems
common that most binary operations between real and complex arguments
would have these argument and return types, and so might be written as
templates using a traits class like this, and even the body of your
F__convn__ function might be something we can generalize and share as
I think that might be a fairly common structure in Octave.

Also, we already have a more extensive set of traits like this set up
for the integer types (see liboctave/oct-inttypes.h).
