Thanks for your continued effort.

That's unfortunate. If you need someone to champion the paper in person
though, I can help with that.

I think you're also in a tough position because the paper isn't broken down
into smaller pieces. std::mul_wide (should be std::widening_mul now though)
is a total no-brainer, and the design is obvious. It probably would have
been in the standard already if it was separated. std::carrying_add and
std::borrowing_sub could be one separate paper too. Last but not least,
anything related to division would be in a third paper.
