There is not. Please submit a feature request.

One of the reasons I didn't add one is 1) the map can be used as a set (if a bit wasteful in space) and 2) merging has some special cases that can avoid conflicts which I wanted to pursue (e.g. if two snapshots add to a set, both adds can be merged without conflict). However, I never went back to create the set once merging was added.

Where are feature requests for Compose made? I don't believe the project is on GitHub?
