Byteswap but not bitswap

[ccuser44]

Recently Luau added the bit32.byteswap function.
One would expect bit32.byteswap to
This would be very useful for changing the endianness of data which could easily be done with bitswap + bitwise shift as I expected

Byteswap could easily be implemented with bitwise extract + bitwise shift and bitwise or. Bitswap cannot.
So if not for changing endianness why do we even have byteswap but not bitswap? Byteswap just seems like bloat

Byteswap is provided to change endianness.
It is directly supported by x64 processors with a bswap instruction and arm processors using rev instruction.
