Although such 9.0 clients support memfd transport, they have an iochannel bug that would break memfd audio if they're run in 32 bit mode over a 64-bit kernel. Influence them to use the POSIX shared memory model instead.
Also bump the protocol version to exclusively mark such v9.0 libraries. Check commit 451d1d676237c81 for further details.
