You've never found a use for one, but bash should provide one because
there's no documented alternative?
Bash already provides one. You're just leaving it undocumented so
you're more free to get rid of it in the future?
I'm leaving it undocumented to discourage its use, yes. One thing I've
discovered is that you can never remove a feature (e.g. $[expr]).
Is it useful enough to add a parameter transformation for it? What should
bash use for the operator?
Did it originate in
another shell?
No.
