We get support expectations if we don't mention it as not being supported. So, 
since this driver is not supported the documentation for QEMU should state 
something along the lines of 'this driver is for experimental or testing 
purposes and is otherwise unsupported.' That's fair to the user and maintainer. 
Nevertheless, if the documentation (or as a matter of fact the code) was to 
claim that VM / TPM state migration scenarios, such as VM snapshotting, are 
working then users should be able to ask someone 'how' this can be done with 
the mssim protocol **today**. Since I cannot answer that question you may need 
to find a way for how to address this concern.
