All this instances can be found and "fixed" without adding manual
CONFLICTS. What you did is add yet another set of redundant entries that
are highly likely to be outdated at some point without any indicator
whatsoever that they are really needed. As such, it is obscuring the
real cases. As such, IMO the correct way forward is to remove *all*
CONFLICTS unless proven that they are required for dealing with issues
outside the scope of the existing automatic check.
