The silver lining is that the reply wasn't "wrong, this is intentional" or "won't fix" but more "please provide a paper" <shrug>

Do you plan to work on the paper ? We probably need to re-admit _BitInt to std::byteswap (P3666R4 8.2.9 currently excludes it) and relax the padding-bit Mandate so _BitInt(48), _BitInt(80) are accepted, but <sigh>
