There are plenty of projects where 6 and 8 pins are fine.

The point was that it's often more appropriate to get a bigger PIC than to
perform unnatural acts to make I/O pins peform multiple function.

I got the impression from other questions the OP asked that he is a beginner
and a hobbyist.  So even if a bigger PIC costs a little more than external
hardware, it will get the job done reliably with a lot less futzing around
trying to figure out why it doesn't work.  This logic makes sense for all
but high volume products, or maybe very space constrained products, although
the extra hardware to make pins do double duty probably takes more space
than the increment to a bigger PIC.
