The Pentax-brand F 2.8 100mm Macro WR, for instance, is FF compatible and was introduced only in 2008. WHY Pentax decided to make THAT lens FF compatible but continued to release other lenses that were APS-C only, I have no idea, but I'm glad they did.

This has a simple answer. The DFA100 was originally introduced early on when there were still many film photographers and they needed a macro to cover both film and digital.  Also I suspect the design of a macro lens means there is not much space saving to be done for an APS-C only macro lens.

The current DFA100 macro is the original macro with WR.
