Distros tend to update those in sync, so this doesn't help much for the
average user, this change would likely cause spice detection fail on
almost every released distro ...

Just checking "SPICE_SERVER_VERSION >= 0x000b01" doesn't work?  I'd
expect spice-server 0.11.1+ having a dependency on a recent enougth
spice-protocol so you can expect QXL_IO_MONITORS_CONFIG_ASYNC being
present then, no?
