Wouldn't this be responsibility of whomever care?

I mean, like any other back-end / plugin that people dump in ToT to
help them "have third-party code hanging out but is not actually
tested and should be fine as long as it doesn't break anything else".

We seems to be gathering more and more of those things lately, and I
thought people were generally ok with it.

Not that I care too much, I don't have any use for MPFR myself, just
wanting to understand where we cut the line.

cheers,
