it should be possible to remove people from a team quietly

[This is a request aimed squarely at commercial use of Launchpad
 (e.g. Canonical's internal use), I realise it has no particularly
 legitimate use case for open source projects.]

In certain circumstances (e.g. when someone leaves the company) we
need to be able to quickly remove them from a bunch of private teams
which control access (e.g. through OpenID) to private resources.
However, we sometimes don't want this change to be widely announced.
With the current Launchpad system which announces any deactivation to
the team owner as well as the deactivated party, this is hard if not
impossible (e.g. if the team owner is another team).

It'd be very useful if there could be some option to not notify the
team owner (similar to mailman's remove_member --noadminack). This
could be limited to ~admins, if abuse is a concern.
