Hmmm, no. Not really. I mean that, I thought long and hard. They're
all so very different, on everything from 10F to 18F, and they have
very little in common

Tell you what though. I've got the current project at a stage where
I'm happy to leave it for a short while and look into relocatable code.
Then I can assess it for myself and see whether I really would benefit
by switching

Hardly ever. I think we must work on quite different projects. It's most
uncommon for me to need modules that were used in other projects

Yes, I appreciate that, and I'm not defending absolute coding. Partly
because it works fine for me so from my POV there's nothing to be
defensive about

Honestly truly - no. As I generally make and assemble the first prototype
PCB by hand, using even TQFP / TSOP / SMT, I think carefully about
pin usage beforehand. It seldom needs changing, and then only minorly

Problem as opposed to the chip in situ doesn't work. And it always
