I don't like this change. The value to check for P0734R0 support is
still 201907. If you want to also check for P0848R3 support, you can
use 202002. So I think it would be better to move the P0848R3 row out
of the rowspan group, and then put 202002 as the macro for that paper.

This one looks fine.
