You might want to fix those in a separate patch set then. Just because
something is in the source tree doesn't mean that it's worth copying
into new code/documentation.

Yes, that looks better.

Couldn't you just return a "NotSupported" error to
EnableIntermediateMeasurement?

I suspect there are several messed up LE APIs and implementations in the
source tree, so I'd say it's highly advisable to not just blindly copy
from the existing code but also use some common sense and be critical of
what you see.
