Until it is a proposal, it's your time to waste, but so far every committee
member who has spoken in this thread is against just removing it from C++17
on the technicality that the space optimization is not required by the
standard.  I'm pretty sure such a proposal will not take up much committee
time.

Removing useful functionality that users depend on without providing a
suitable replacement is very unlikely to pass. (And much as I like Boost,
pointing users to Boost is not an acceptable substitute.)
