Absolutely, I agree with this.

However I will point out that shell scripts can be evil, since virtually
every command or expression in a shell script involves forking and execing
some Posix.2 program, and this process is virtually instantaneous on Unix
but takes seemingly forever on MPE.

So if your "menuing" is a bunch of shell scripts then it might be a lot
slower on MPE (and have somewhat more of an impact on the rest of the
system, but probably nothing extreme) than on Unix.
