Without EMUL it becomes a much larger and more tedious process to multiply 64-bit values. But yes, it's only usable for signed multiplications. Which is annoying. (And is the same problem on the PDP-11.)

Turning a signed multiply into an unsigned one isn't very hard.  Unsigned div is another matter, unfortunately.
