Not as overboard as it might sound though - say for example that we make
a payload specifically to populate the legacy tables.  A boot menu could
offer the choice between Windows and Linux, and if you chose the Windows
path it would run the legacy table payload followed by the windows loader,
while the Linux path would just run grub2 (or FILO).  Its not a crazy idea,
and its the sort of thing we need to be prepared for.

Sure, but lets get more technical - how is this going to work?  Who is
going to write the configuration?  How would one change the configuration
(probably at the same time they are adding something to the LAR?).  Should
we have a simple text file on the ROM?  XML?  Something else?
Many questions, few answers.
