Why? Can't you fix rEFIt instead?

That will lead to trouble. The BBP is a shared resource, like MBR. If
installing GRUB to a partition made use of it, it could overwrite other
things, which users wouldn't appreciate.
Besides, the whole notion of "installing a bootloader to a partition" is
specific to DOS-style labels anyway, and used only for compatibility with
Microsoft. There isn't any real benefit in trying to archieve the same
thing on GPT.
