Why? A UART can be bit-banged (done in software), or another way of
commuication can be used (check my WLoader and ZPL bootloaders).
[Reading further in the discussion I see this point has already been
made for me.]

But the real problem is that I don't know any 8-pin PICs that can write
to their own code space.
