Most people in the free software licensing community either think so
or have no opinion on the subject, based on my latest finger-licking.
The good people at MIT have denied that such an interpretation was
intended by them, saying that it contravenes their long-established
patent licensing policy.

AFAIK, neither MIT nor any other licensor has sued for patent infringement
(and a good thing too) in a situation where the question of implicit
licensing might arise.

I'd urge you to explicitly structure this as Apache 2.0 + limitation,
as that it makes it much easier to understand.  There's nothing like
having to scan a long stretch of legalese, wondering just wherein it
differs from a base license that you already understand.

First known example of political correctness:   John Cowan
After Nurhachi had united all the other
Jurchen tribes under the leadership of the      cowan at
Manchus, his successor Abahai (1592-1643)
issued an order that the name Jurchen should       --S. Robert Ramsey,
be banned, and from then on, they were all           The Languages of China
to be called Manchus.
