My gut reaction is that leaving a reasonably sane set of default quotas
is a good thing.  I would imagine almost every environment wants to have
quotas in place, and some of these things are more likely to be changed
than others.  For example, it's nice to be able to bump up the number of
instances, but without having to go through and decide on a value for
*everything* (like injected files, injected file size, ...) and just
leave those at the sane default that we ship with.
