So? Boot index is used exactly once - when the domain is started. After
that, you aren't booting any more, so what benefit is there to changing
boot index on the fly?

virt-install manages to install guests just fine without changing the
boot index on the fly; it manages to sequence multiple qemu runs with
different boot indices between runs.

You're welcome to submit a patch if you think you have a use case; but I
personally don't see the current setup as limiting.
