I'd like to add that every exception approved adds up to create moving
parts at a moment where we want to slow down to let QA and Docs and
other downstream stakeholders catch up.

Obviously, things that are already approved and working their way
through the gate should be in early enough to limit this disruption. But
in general, targeting more than 25% of your juno-3 velocity to -rc1 is a
bit unreasonable. For Nova, that means that more than 7 exceptions is
starting to be a stability issue.

Please keep that in mind every time you go to support a FFE.
