I've thought about this since you've mentioned it a couple of times. And I
can't see how it's a problem.

With either scheme, we have 12 bits of major number. If we obsolete the
numbers we use now (0 to say 99), we loose those numbers in either scheme.
How is that "wasting another part of the number space?" We had 4096
majors, and now we have 3996. ??

Take care,
