You’re right, that is one of the advantages of CRDTs, but it turns out to be hard to realize on the web — aside from RTC (which has its own dragons), you still need a server in the mix.
The other thing an authoritative server solves is persisting the data. Because one server is the authority for a document at a time, you can use S3 or R2 for persistence without worrying about different servers with different versions of the document colliding and erasing each other’s changes.
Oh, this is interesting. Can you elaborate (or link to some post) about what sort of issues you run into? I find the concept of CRDTs to be very interesting, but if you still need a centralized server I question the value of them over OTs. I'd love to understand more about if this is a connectivity issue, a CRDT issue, or what.
