Why do you want grub installed in MBR? I don't think any GRUB would fit into 446 bytes.

I guess you mean one of the options often used with legacy grub:
1. the space between MBR and the first partition
2. the unused space at the beginning of a ext[234] file system

Which one? And how much space do you have there?

I was playing with GUID Partition Table on both my laptop and the EFI
server and used a dedicated BIOS Boot Partition to hold grub in both
cases.

Probably just an  optimisation issue. And optimisation is the thing to
do last, when everything else is working. Unless your case is a very
common one.
