[development] GPL policy: request for clarification

The GPL appears to allow us to combine GPL and "compatible" code in a single
GPL-licensed package. Can we include such code in drupal.org CVS?
This is a pressing issue because there is considerable interest in using
jQuery), at least in contrib and possibly as candidates for core.
Our CVS policy states "All code must be licensed under GNU/GPL"
The practice has been to interpret this as meaning that open source
libraries with "MIT" or similar licenses may not be included in Drupal CVS.
However, the Free Software Project has designated a number of licenses,
including the "MIT" license, as "compatible" with the GPL, because they
impose no restrictions that conflict with the GPL, see
GPL FAQ specifically states,
http://www.gnu.org/licenses/gpl-faq.html#WhatDoesCompatMean, that the GPL
permits you to "combine code released under the other [compatible] license
with code released under the GNU GPL in one larger program" privided that
"such a combination ... is released under the GNU GPL".
In other words, apparently, we can GPL the combination of GPL code and code
with compatible licenses. So, it appears, we should be free to include "MIT"
and other compatible-licensed code in our CVS and releases, provided we make
it clear we are thus GPL-ing the combination.
So, can we go ahead and put such combinations in CVS?
Can we consider/propose them for core?
