Per Alvaro’s above comment, if this is something low-risk that could prevent
the “emergency patch” scenario later on when we actually need such
debugging flags in place, I would be ok with getting this in prior to Beta 1.
After Beta 1 I would be more risk adverse and go with Andres’s statement
around urgency and wait until the PG12 commit cycle.
And of course, we should come up with a policy, too, but I think we could
kick that can just a bit farther down the road for roughly 2 more weeks.
So +1 if we can commit this prior to Beta 1.
-1 if it waits until after.
