Will discuss tomorrow on call

@xavierchanth what's your preferred option (and why)?

I think it's fine to go into these things with an answer (and other things that were considered). Maybe it surfaces additional reasons for the other options to be (re)considered, but generally I think people will be happy to go with the suggested approach.

As I recall, the purpose of this ADR was to leave a record of why we started doing the thing, so let's not agonise too much over how we do it.

My plan is to try A, and see if it reasonably fulfills our needs, if not, we can try B or another option if it appears. Once we have a clear answer, I'll update the document.
