It's not _that_ useful.
But old assemblers that we still want to use *NEVER* have support for
newfanlged instructions, so we always add new instructions with ".byte".
Then, a few years down the road when we've moved to just old assemblers
instead of super old assemblers, we move to the real instruction names.
This is all business as usual.
