I'd agree Relay is relatively far along, compared to other frameworks. I might lump its support into a few groups: - Full (eg. request batching) - Full, but painful (eg. colocation) - Partial (eg. mutation queuing) - Non-existent (eg. durability guarantees) (I've been using Relay Modern daily for a few years.)
