I agree here. I briefly urged against using the less used TOML format, but
I have no real skin in the game around packaging. I like YAML, but that's
also not in the standard library, even if more widely used.

But given that packaging is committed to TOML, I think that's a strong case
for including a library in stdlib. The PEP 517/518 authors had their
reasons that were accepted. Now there is broad ecosystem that is built on
that choice. Let's support it.
