I'd be curious how a previous truncation on a file can tear down a PFNMAP

Unfortunately, forbiding it may not work for vfio, as vfio would like to
allow none (or partial) mapping on the bars.. at least so far that's the
plan.
I think vfio should handle that memtype reservation manually, as you
proposed. So that shouldn't block that IIUC.
