I strongly suggest not to backport individual commits out of order but follow the process described in #1496.

As in backports to older distros should be done periodically in big batches like #1477? Is this what that process looks like?

1. [Noetic] Update maintainers #2075 should be included in the next Noetic release
2. After some soak time it should be included in a batch of backports from Noetic -> Melodic
3. The backports should be released to Melodic
4. After some soak time the backports should be included in a batch from Melodic -> Kinetic
5. The backports should be releasd to Kinetic

Does the process have a gap between merging a PR and releasing it, or merging backports and releasing them?

Correct.

That is up to you and the confidence you have that it doesn't break anything. A longer soak time allows you to catch regressions in e.g. Noetic before even backporting and releasing a change into Melodic.
