The only reason why we did not include <subtitle> as a separate element in
MODS is that we were trying to keep the number of elements at a minimum to
make for easy metadata creation and generally a less complex format than
MARC. MODS is not supposed to have an equivalence for every MARC element.
In the case of title/subtitle, we thought it could just be concatenated
without separately identifying subtitle.

Do others see a rationale for separately identifying subtitle (other than
the fact that MARC does)?
