.... Pentax already has developed lenses that were not compatible with older cameras, e.g., FAJ lenses, DA lenses on older bodies with no aperture control or many (most?)

The discussion here is about old lenses on new bodies, not new lenses on old bodies.

I was reacting specifically to your comment that Pentax should not release new mirrorless mount lenses that are not compatible with DSLR (old or new) bodies.

Did I say that? I don't think so!

I've certainly said they shouldn't do so unless there are specific benefits from doing so. Such as better image quality from wide-angle lenses, or perhaps a lightweight option for a walkabout Pentax new-mount mirrorless camera and a mid-range zoom:

My apologies, it was my (mis-)interpretation of "I have said elsewhere that if Pentax develops a new mount, they should only develop new lenses for it if there is a clear benefit in doing so. If a new lens can equally work with K-mount SLRs or the new mount, it should be developed as a K-mount lenses."

For me the lightweight (and slightly smaller size) option you just mentioned justifies a number of new lenses.  If I stubbornly stick to APS (hey, I'm allowed ;-)) then what is the point of a DA40 Ltd "pancake" lens if you need to add an adapter!
