Have we ever actually deleted such flags ? I added that comment
a few years ago, but didn't think we'd ever deleted any flags,
as doing so will prevent us from loading the saved state XML of
any previously running QEMU.

Now, we won't actually support managing such an outdated QEMU
since it is going to lack features that current code assumes
will exist. 

In the case of kqemu we can be confident no such running VMs
exist anywhere in the world, but other features it is not so
