Well, I think it would be good to have 16F support since its widely used
by hobbyists.
I also don't like the low voltage programming mode. And I think a lot of
others don't either.
And I've forgotten that I have one board which actually uses a 16F part.
(Because its cheap [16F630] and I don't need the speed with this
particular board).
