Keeping to the exact truth is a very good thing.

As I'm sure you know, it's perfectly legal to combine GPL and X and BSD
code into the same program.
However, what I believe you're pointing out is that: because the DFSG
doesn't provide exactly the same guidelines as the GPL, it's possible to
have DFSG code which can't be combined in the same program as the GPL.
[Then again, the same goes for other combinations of DFSG licenses.]
It's probably worth pointing out that DFSG was never intended to make
sure that all debian programs could be combined arbitrarily to create
new programs. Otherwise there are some significant programs we'd have
to kick out of main.

Basically, I think you want to derive something with the transitive
["viral"] qualities of the GPL which still allows any DFSG code to
be combined with it. But this can never work because, for example,
the DFSG does not prohibit a license from having a clause of the form:
No other licenses may be applied to this program.
So you'd have to derive a new DFSG as well, to make this work.

I hope that my comments make sense to you.
