Which OSes are you thinking of here?  Linux currently supports (assuming it 
works well enough for read access) the boot filesystems of everything that 
runs on Xen, plus more.

It's a fair point that it increases effort for OS maintainers if they have a 
grub driver for a filesystem that Linux doesn't already support - I'm not 
clear what this could be though.  Are you thinking about ZFS, perhaps?

I suspect given the choice between kboot_sl and grub some users might prefer 
kboot - it is more featureful (apart from the graphical loading, I suspect it 
might actually be a superset in terms of features now).

We can always make which bootloader is used be configurable (even per domain - 
perhaps we could have an unprivileged interface), anyhow.

Cheers,
Mark
