In other words, both of you agree with my original points, even though
Mark said first "I agree with Paul", and then gave the same reasons as
me for not putting non-shared stuff in sysdev. :-)

Anyway, I don't care enough to try to persuade anyone to change stance
on the question, I mostly wanted it clarified before it gets out of hand
in case it is NOT to be a dumping ground.
