Yes. I agree it is complex. We have given it fairly a bit of though and if
you want to support legacy applications then it is pretty much about the
only way to do this.

Sure we could go LinuxBIOS version of grub, but unless you add "legacy
application support" it won't help you with booting anything else other
than linux. So while it may fit with your particular problem, usefullness
of such hack won't be as big as one could expect.
