We *are* going to have similar hacks. That's not a question. At this
point, the live pool of EFI systems is functionally zero, so it's
pointless to try to draw conclusions from the live pool (the little I
have heard about the incoming set of EFI machines make me think the
problems we've had with BIOS will look like child's play compared to the
EFI braindamages we'll have to suffer.)
Perpetuating this hack will cost a few kilobytes of memory on machines
which may not care. *Not* perpetuating may save a few kilobytes on
machines which may cause odd behaviours that only are noticeable when
you, say, boot from one OS into another.
Guess which option I think is saner.
