I've been thinking about that.  Considering the size and age of the code
involved, it sounds a little risky, but that is counterbalanced by all of
the new tests.

Do you feel like adding a few coreutils tests that currently fail
on common platforms but that would succeed if coreutils switched?
E.g., here:
  coreutils/tests/seq/basic
  coreutils/tests/misc/printf

Have you tried and compared code size on a modern Linux/libc system?
