GPL-2.0-only is compatible with GPL3, so why does that matter? And MIT 
is compatible with BSD-2-Clause, but we don't include that. 

Are we okay with GPLv4, v5, ...?

What I really care about is having a free-for-all and having a 
proliferation of different licenses and combinations of licenses under 
bindings. If everyone paid attention, then I wouldn't care. But they 
don't and just copy code around. We already have a license mess with DT 
headers and .dts files. Besides the copying problem, it is not hard to 
find GPL only license included in dual or BSD/MIT only licensed .dts 
files. Seems like an issue to me.
