P0829 (the old omnibus paper) recommends making the integer overloads freestanding.  I haven't made a smaller, split out paper for charconv yet.

For the floating point overloads, there are two major challenges.

First, is the floating point part.  It is my (weakly held) opinion that floating point functions shouldn't be required in freestanding,

I'm not even sure the FP charconv functions should be required in a hosted implementation :-P
