Would Infra need to maintain the authz , or would that be something that
you do?

Note: we already have a separate authz for openoffice-security and
openoffice-pmc, for the same reasons -- there are some things that should
not be authorized for all committers.  Going from 3 authz's to 4 is not
unreasonable, IMHO.

None of these get automatically included in releases that are installed on
tens of millions of machines.  So I would not ask for additional controls
here.  I'm asking only for additional controls on source code.

I'm not concerned with things where social enforcement would work.  It is
not a concern that someone unqualified makes a change to the source code
merely because they have permissions.  The issue is that the product is so
well-known and so broadly installed that it is automatically a target for
hackers, and with so many authorized user accounts from committers who are
not actively coding, or never were, that these authoriziations are
particularly vulnerable to compromise.

I believe this a serious issue and we act irresponsibly and do a disservice
to our users if we treat this merely as an inconvenience or a social faux
