I'm obviously in favor of this proposal.

Only really comment I have is on printf(): You're right that we have %f and
%F to toggle locale-sensitivity, but the %e, %E, %g, %G formats are always
locale-sensitive. It might make sense to introduce locale-insensitive
variants of those, especially considering that %G is considered the
"standard" floating point format. Internally we support %H for that, so we
could expose that... (Alternatively, locale-sensitivity might be removed
for e/E/g/G.)

Nikita
