Thanks Victoria for the great writeup, with a thorough analysis and trade-offs. I do not have any major questions about the proposal.
Just one thing that might be out of scope: if users want to enable the versioned table feature across the topology, should we allow them to do it via a single config rather than changing the materialized object at each place? Maybe we can defer that for future discussions, but just want to hear your thoughts. Anyways, I think this proposal is great just as-is even if we agree to do the configuration improvement later.
