I think that was merely a means to keep producing a lens that continues to sell reasonably well on its own merits to both APS-C and full frame users. There are virtually no brand new SMC FA35/2s available here in the UK now, and none from main Pentax dealers - which supports the notion that it was still selling. Plus, the street price of the "new" HD model has quickly fallen to around what the old SMC model sold for (I paid even less for mine). I suspect Ricoh had simply run out of SMC glass, or something like that, wanted another production run of the lens, and probably felt they had to at least make it cosmetically coherent with other modern Pentax gear. The HD model was just a low-cost, minimal development option to keep a popular lens alive whilst they worked on more important things.
Optically, the FA35/2 design still holds up very well today - especially at f/2.2 onwards. I'd have been overjoyed if it was WR and had near-silent focusing, but less so if PLM AF resulted in focus-by-wire MF.
I imagine the next Pentax lens at this focal length will be an even faster D FA* model to sit alongside the 50mm and forthcoming 85mm lenses...
