I don't think any of the "pros" do. AFAICT, it's just
eye-candy to lessen the initial culture shock for Visual-C
programmers. ;)

That's what I used to do, but I had a hard time keeping track
of what I had changed from the defaults. Now I find it easiest
to write a shell script that creates a source tree. It seems
like a bit of a hassle at first, but you're always sure what
you've got (all your tweaks are in one small file) and you're
always sure you can repeably generate the same source tree.
