How do you count how rare is a feature need in languages that don't support
that certain feature? I think you have no proof of what you are saying.
On the contrary, the only evidence I see (looking at lot of real code written
by other people), with languages that do offer multiple return values, like
Python, Go and others, show that people do use this feature very often and
appreciate it.

Maybe, but we'll need better unpacking syntax at the calling/use point:
auto (x, y) = foo();
foreach (auto (x, y); genPairs()) {
There is a pull request, plus a good amount of discussions, on this topic.
