The comment at line 29 "C++17 20.19.3.(7.1) explicitly forbids '+' here" seems to be outdated

not really, in fast_float version of 3.10.1( current is 3.8.1) https://github.com/fastfloat/fast_float/blob/main/include/fast_float/parse_number.h
was added
#ifdef FASTFLOAT_ALLOWS_LEADING_PLUS // disabled by default
if (*first == UC('+')) {
++first;
}
I created pr in apache arrow for updating fast_float version but i don't know when it will merged or will it be merged at all. So for now we could use this.

Apache Arrow used [https://github.com/fastfloat/fast_float](fast_float lib). In latest version was added same code but in preprocessing block that undefined by default. Updating to latest version require al lot of code changes inside arrow, ci. So it will be easier to add this block directly to dremio until the version will be updated in apache arrow repo.
