why not a grubcheck option?

[John Beamon <jbeamon franklinamerican com>]

I may be a little behind the curve because I work primarily with 7.3 at 
work and 8 at home.  Still, the only preinstallation check I see 
anywhere is "lilocheck", and grub has been the default bootloader 
supported and installed since version 7.something.  Why isn't there a 
grubcheck yet, and how else would I implement this sort of feature in a 
grub-based installation?
