A new network version could add a command 'getextensions' to query the supported extensions, returning a list of extension strings or (extension,version) pairs. For BIPs some something like 'BIP0064' could be defined, but for an experiment for example 'experimental-getutxo'. This would be easy to implement and specify. Unlike with the 64 service bits it does not require (as much) central coordination to assign as there is no real danger of collisions. It takes the political aspect out of P2P network extensions, and gives more freedom to alternative implementations to experiment with their own extensions. And no more need for bitcoin core to drive what must be supported with increasing network versions.
