That probably makes tracker a good experimental app to see if replacing the
existing localperms based security by container based security brings in terms
of readability/maintenance, performance, flexibility... A good vsprint topic.

Good to know.

Maybe because you fixed all the concerns I add when I tried to use it, but the
idea was that rql rewrite stuff would allow to have two relations available in
RQL (eg an "application" relation and a "generic" relation, the generic one
being a superset of the application relation for use by container) while only
one would exists in the database.
