Fwupd supports a "requirements" option on firmware. This allows manufacturers to prohibit installation on particular software combinations. If firmware doesn't work properly on fwupdate 10 then the manufacturer should be setting the requirement on com.redhat.fwupdate to 11 or 12. This was discussed upstream recently due to some Lenovo failures with fwupdate 10.
If Ubuntu picks up a patch on 10 then that requirement won't be satisfied properly. So please bring back version 12 to Ubuntu rather than a single patch.
One more dimension to add to this.
