  I think an outcome of our VC yesterday was you were OK with this. IIRC you thought this was a server-side thing. When in fact this code runs on the client and is inventing e.g. `command-changeset` capabilities so code can check for the existence of a command via an artificial capability. In the future, v2 peers will likely expose the raw capabilities dict and we'll do something more intelligent for sniffing features.
