In the big picture that's irrelevant. An attorney's job is to protect
their client or employer.

Generally no because "You may apply license X or license Y" type
statements are built upon hundreds of years of caselaw, dealt with
regularly already by companies dealing with open source and in general
don't need lawyers to peer at it because there is already clear policy.

The last thing the kernel needs is two, then three, then five then ten
different funky supposedly compatible with GPL licences where it relies
upon someone saying they are compatible.

That has lead to historic problems - long ago people naÃvely assumed
BSD 4 clause was GPL compatible. Then the lawyers realised it wasn't
then you have a mess.

If you proposed a chunk of code that was a long term maintenance pain
in the butt Linus would tell you to take a hike. Why is it different
when you are doing the same by trying to introduce weird, un-necessary
licence complexity ?
