I think this is a possibility. Just get rid of ranges entirely and make everything replaceable.
yup, and it's not hard for relays to adapt so they usually just send teh new version, but if the new version has a "replaces" tag you can ask for that event by ID and it has etc back to the first
it would make finding them a lot simpler too, i should point out, and you can put both tags in the interim it would only take me a few hours to add this function so that it gives back only the newest of a chain of events with replaces... just kind and pubkey has to be the same
