Dominique,

Thanks for the response. We discussed Boost.Compat but decided it is outside of the scope. For instance <latch> is what set off the discussion and it can be implemented in ~100 LOC. This implementation of charconv will be around 10k LOC so it should be in its own library. If the demand signal is to use std::error_code instead of errno we can make the change.
