Robert Scholte commented on MNG-5227:
-------------------------------------
I've been talking about this change with a couple of fellow committers at
FOSDEM and it convinced me that you never ever want to manage {{optional}}.
They have too much effect on the dependencies using it. For dependencies which
are expected to be non-optional (default) it suddenly will be. Instead the
ModelValidator should inform the users that setting the optional-flag on a
managed dependency has no effect.
> The 'optional' flag of a dependency should be manageable.
