no, it's not. if it was, then they wouldn't be making the proposal.

no, i don't.
a person expects debian and *bsd (and solaris and aix and ......) to be
different.
they DON'T expect one debian system to be that different to another,
depending on when it was built or when it was last upgraded.

i wouldn't.
i regularly have to modify scripts written on one *nix-like system so
that they will work on another. it's not in the least bit surprising. it
is *expected*.
and it's not just bashisms, almost all of the standard utilities (incl.
awk, sed, grep, cat, tail, find, du, df, nice, ps, time, and hundreds
more) are different from system to system. that's one of the reasons i
install the GNU utilities in /usr/local on any system that doesn't have
them so i only have to change the PATH to get the good GNU versions.
IMO, the GNU versions *ARE* the standard. they're available for every
unix-like systems (whereas, say, solaris' or AIX's or HP-UX's versions
of tools are ONLY available on their respective systems).
