For single binary / heterogeneous emulation, we'd like QAPI to
be "feature-agnostic". In particular, using the example of KVM accelerator, whether a binary can run with it built-in or not
should be is irrelevant for management applications: they should
only check if it is used (enabled).

The following series is adding KVM specific structures and commands:
https://lor= e.kernel.org/qemu-devel/20250409082649.14733-2-zhao1.liu@intel.com/
It could be interesting to discuss if this can be avoided. But this
can also be discussed on the mailing list (as it is still currently).

Would = it be possible to just mark the commands as "do not autoregister"= and then do the registration (for example) at machine/accelerator/CPU crea= tion?

I think qemu-ga al= ready has a similar run-time registration model but I don't know why QE= MU does not use it.
