We probably will at some point, but I don't know that it's a huge
priority right now.  The PXE booting method works fine, and as I
mentioned we don't intend you to reboot machines without using the
undercloud anyway, just like Nova doesn't expect you to reboot vms
directly via libvirt (or your driver of choice).

It's likely there would be other issues booting a deployed machine if
the undercloud is down anyway (nothing to respond to DHCP requests, for
one), so I don't see that as something we want to encourage anyway.
