That is a reasonable argument given the lack of semantic factoring in the LCSH as a whole, but is less compelling outside that model.
A good example of how precombined terms add complexity can be seen in the establishment terms for Fantasy:

Also, this record makes me wonder what fantasy literature about subject headings would be like: http://id.loc.gov/authorities/subjects/sh85129432.html .

Simon wrote “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.” The ALA Subject Analysis Committee’s Subcommittee on Genre/Form Implementation’s Working Group on the Definition and Scope of Genre/Form for LCGFT investigated this by consulting numerous general and specialized reference sources and came to a different conclusion. In a report of its findings it said:
“The terms genre and form are often used interchangeably in authoritative sources, and even when differentiated the resulting definitions are inconsistent and contradictory--formal structure is often cited as a key aspect of genre and intellectual content is considered as a key aspect of form. Many approved genre/form terms represent resource types defined by tightly bound intellectual content and formal structure.”
They recommended that LCGFT not attempt to define and present “genres” and “forms” as meaningfully distinct concepts.

This is not quite correct; fixed fields* can be treated as just another kind of property. Alternatively, fixed fields can be mapped to Classes.
For fixed fields that have a limited range of values, the values can be represented as IRIs. For some fields mapping to class membership
For a fixed field that is either yes or no, the value can be a boolean data property, though membership of a class or its complement may be appropriate.
For a fixed field that takes a numeric, date, or interval value, a data property is appropriate.
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.

* I'm using "fixed field" to refer to the various logical parts of the "Licensed to Kill" control fields, plus the appropriate parts of the leader.

Every IRI is the equivalent of a MARC fixed field -- that is, a coded, identified value.

?having this genre term is the easiest way to find what electronic

to search by a fixed field. Also, will Bibframe have the equivalent
of MARC fixed fields?
