Not sure anything in the offline-first ecosystem qualifies as "boring" yet. You would need some high-profile successful examples that have been around for a few years to earn that title
The Rocicorp team have decided to focus on a different product, Zero, which is far less "offline-first" in that it does not sync all data, but rather syncs data based on queries. This works well for applications that have unbounded amounts of data (ie something like Instagram), but is _not_ what we want or need at Marco.
