Of course. But I don't think you're going to deny that what it (or
really its ancient predecessors) specified has been taken by
assembler implementations as reference.

I clearly disagree to this last statement, and I think you saying so
contradicts you having pulled in people maintaining other assemblers
apparently in the hope that they would support your position (which
they didn't, at least not publicly, i.e. not visible to me).

Furthermore you once again ignore the fact that the assembler
after my proposed changes isn't going to reject the previously
supported format, it merely _also_ supports the SDM specified
variant. Hence I don't see the change breaking anything, and I
continue having a hard time understanding your position in the
first place.
