I concur. It's already been demonstrated that almost all the modern (ie

modern Pentax glass (DA and DA*; ~$4K replacement value) and I am not about
to add all new lenses to go along with a FF body upgrade. Not happening.
Where and by whom? Kenny?
There's a sticky thread at pentaxforums where they maintain the results
of individual tests (including some from Boris Liberman) ...

Boris' collection of test shots (some via Derby Chang) here ...

There are a few question marks, like the DA* 200, but the majority of
lenses have one problem or another (even hood geometry issues) on FF.
Apparently the DA* 60-250 and possibly the DA* 55 are fine on FF. These
tests were conducted on 35mm film which is larger than present FF
sensors, so some lenses that vignette on film may not do so on an actual
FF sensor if it existed.
FWIW, Ricehigh has his own table here ...

and arrives at differing, but similarly pessimistic (but what would you
expect?) results.
