We are, and you know my opinion that OCF_CHECK_LEVEL is hideous
(although lmb, for one, seems to disagree). But dropping it now does
clearly count as a regression and I'd really hate to see that happen unless

a) there is a replacement method for tuning the thoroughness of checking
the resource state during monitor, _and_
b) there is an automated or semi-automated ("cibadmin --upgrade"?) means
of transitioning off OCF_CHECK_LEVEL and replacing it with its successor
feature.

Cheers,
Florian
