I've been in this "use the old stuff for portability" camp for some time,
but now that you mention it....I can't think of any systems I use that

What an interesting epiphany. It reminds me of the time when first I
realized that continuing to write K&R-style C was no longer necessary, as
everything that I used had an ANSI-compatible compiler and supported
function prototypes.
Seeing backticks in the rearview mirror is a welcome change.

Portability to what? The POSIX $((...)) arithmetic expansion is widely

Some of the other things are more esoteric, but you should be able to
increase your expectation to POSIX features and still be sufficiently
portable.
Would anyone who uses Bash regularly, both
interactively and
for scripting, really want to go back to using the V7 sh
for production work?
I have never used all the fancy stuff in BASH such as the arithmetic
functions; I still use "expr" etc for portability.
