I understand that this is a pure relay, and that no data is stored.
It's a nice feature, since it's probably very cheap to run for thousands of users.
However, it also means that data will only sync when two devices have Buckets opened.
For self-hosted users, both the storage cost and the potential threat of having the buckets data stored in the relay is much less of a concern. Could you please consider an option for which the relay would store the buckets ?
This will be very beneficial as an asynchronous sync will become possible (my wife and I will probably never have Buckets opened at the exact same minute)
Thanks !
