If this were absolutely true (the waters were not muddy) then there
would not have been a second (or third?) generation of OSI-approved
licenses with explicit patent grants.
If implicit patent grants were crystal clear and provided all the
protection required for open source why then almost all modern open
source licenses have explicit grants?

Perhaps. However, there appears to be licenses in the past without
explicit grants of patents and explicitly do not grant trademarks.
Also, there has always been some "muddied" waters with respect to how far
some explicit patent grants in some older OSI approved licenses go with
respect to forks.
The caveat "The patent license shall not apply to any other combinations
which include the Contribution" in some licenses (mostly retired?)
has caused some discussion in the past I think.

I'm not suggesting that. I'm simply saying that the OSI has been
acknowledged as the arbiter of open source by ISO which should be giving
some folks (at least those not so self-righteous in their indignation
that someone would dare submit a license not up to spec) warm fuzzies.
I would hope that the OSI would take the opportunity to say "yes, sorry,
this isn't open source but perhaps we should think about a category of
"reference software licenses". This might be helpful to the community.
It might not.
However, Creative Commons has a wide range of licenses. Some would meet
the OSD, some, like the noncommercial share-a-likes, would not. While
they don't step on OSI's toes by doing software licenses, if the OSI
simply shows ISO the hand they might go to CC and ask for a wrapper on
their site like for GPL v2.0, LGPL and BSD to clearly explain to developers
their rights and responsibilities under the MXM license. Then display a
That's probably almost as good for them as OSI branding. Yep, they sure
are free to leave. Do you really want them to?
We're software folks. We really SHOULD understand the concept of evolve
or become MUMPS coders. Highly paid, sometimes desperately needed but
mostly irrelevant to the software industry at large (no offense to MUMPS
programmers...just picking an older language at random).
No one is really filling a CC-like umbrella role for software licenses at
the moment and perhaps it is too far outside the domain of open source
for the OSI.

It probably isn't all that clear to many lawyers either without first
reading up on it. Even a few general IP lawyers.
