I don't think the cache is a good idea either, for the reasons you

As for tuple vs reference, I think the general direction is to move away
from references as much as possible, and AFAIK references actually make
things harder for IDEs and static analysis tools, whereas the tuple syntax
array{string, string} is well understood at least by PhpStorm, Psalm and
PHPStan, which can correctly type the function's return value in their
stubs.
