Well we also have the <record/> loggers. Which although not controlled
by the commad line, I think they should have the same rights to events
as "the logger" (otherwise they are useless for debugging sections of
a build).

It you can decide not to issue messages, you can decide to change the
behavior
of your task in a more radical fashion. But nevermind this point.

Still if we want to have such functionality what we would need is an API
in project to check for current "logging level of interest" that
internally
will consult ALL BuildLogger2 instances and give the aggregated answer.
Such a system will work in the presence of <record/> loggers.

Jose Alberto.
