Hm, this portion of Kconfig is a trap in a way indeed - on the other 
hand it is also a useful tool and the simplistic approach to 
disallow select altogether is a step backwards.

IIRC either Vegard or Steve has come up with a patch series that 
improved Kconfig to warn about problem selects while still allowing 
the simple ones. That would deflect most of the bad uses while still 
allowing the good uses. Not sure what happened to that series.
