You seem to be as old fashioned as I am (I grew up with V7
shell).  People complained often enough how antiquated my shell
script (hence many but not all git Porcelain-ish) style is.

I have tried very hard to reject "Hey, it's in POSIX -- we'll
use it and screw platforms that are not exactly POSIX".  I only
use POSIX as a yardstick to decide what to stay away from, as in
"Let's not use ${parameter//pattern/string} -- it is not _even_
in POSIX".
