But note that no OSI certified open source license will grant the right
to use a trademark.  You gain trademark rights by having control over
the quality of the described quantity.  If you give up control (which
the OSD requires), you cannot grant the right to use the trademark, or,
if you do, then you will lose the ability to enforce the trademark.

In the case of derived names like JPython, or IronPython, the PSF would
have to claim in court that "everyone knows that Python is only and
exactly Python, and that anything with prefixes or suffixes may be
derived from the PSF-copyrighted work, but is not an official product
of the PSF."  That's reasonable, but harder to prove than insisting
that no computer language may contain Python in its name without being
the PSF-copyrighted work.
