In regards to the original issue,  genre and form are logically distinct concepts,  and it is not advisable to conflate the two.  Genre is an attribute of the content of a work; form is most often an attribute of the carrier or medium.

It is theoretically and practically better to model the two things separately, then provide an underdetermined union for legacy data.

Big + to separating these out - at the moment it is very difficult to provide good search options because these are mixed up so often - although the way this is spread across the current MARC record + subject headings will probably make clean separation of existing data challenging - but I’m in favour of at least getting this right in the model.
