Luis,

I believe your new MPL is definitely meets OSI requirements.

Having said that: Although not really germane to OSI approval,
I would appreciate clarification of the effect of section 11.3.

So the question is, Alice releases a program under MPL 2.  Bob takes
Alice's program, combines it with GPL code, and releases the
combination under GPL.  Carol receives the sources from Bob
and makes improvements to portions originally contributed by Alice.
What license applies to Carol's improvements?  May Alice take
Carol's patches and, without any additional license,
apply them to her MPL code base?

Note this is a perennial question about the license status
of permissive-licensed code which has been incorporated into
a GPL-licensed larger work.  Since you are adding a permissive
clause to MPL, you might want to give advance guidance.
