. Artistically, are usage patterns even desirable? I'll have to ponder that. More telephoto range is almost free with the Q. So I'm guessing you mean autofocus capability. I think Pentax should have offered a 200 -500 equiv lens or even better updated the Q-PK adapter to AF.

I already used my Sigma 70-300 with my Q-7, but, yes, I am referring to AF usage only. I would have no needs at all if Pentax’s adapter carried signals across - but it doesn’t, so my old Pentax 55-300 is of no real value either. In fact, I really don’t see any value at all to Pentax’s product compared to other adapters - at least, the Metabones adapter would have at least concentrated the light, giving me another f-stop.
