That approach is ok if the category method can't be made to work.
I agree with Miles that it is somewhat undesirable to add a new
primitive for this, especially since it probably isn't necessary:
the category approach can probably be made to work.

To make it work, you just need to create a distinct category symbol
for each buffer (that uses one of those modes).  Do it with make-symbol
so that they won't be interned.

That method probably is not very hard once you try.
