Why? If this is because of the triviality of reimplementing, wouldn’t
they do, once they want to use it in contributing emacs (I keep seeing
many (while (not …) …))? or do they restrain themselves for some
rational/useful reason I still ignore?
The “it’s one macro more to learn fully the language” doesn’t stand that
much (especially about elisp) to me as it is easy to read source code,
easy to find definitions, and “unless” is as much an english word as
“while” (maybe even more widespread, outside of programming).
