I was thinking of ability to give the default entry as regular expression. It would pick the match with greatest version. It would be great, if you have many series of kernels installed and you might not want to have the newest possibly experimental one as default. I guess I should add this as a separate bug report once I find out how.

Addendum: Even the resolution of a variable would be expendable, because a host-individual string can be deposited during installation and remains constant.
Solely the dynamic value reference for "GRUB_DEFAULT" would be the desired killer feature ,-)

For dual boot systems in larger installations it would be a real blessing if grub could read a single byte from the network like so when presenting its menu:

GRUB_DEFAULT=$( cat (tftp)/default-grub/$HOSTNAME )

- or -

GRUB_DEFAULT=$( curl http://myserver.mydomain/boot/grub/$HOSTNAME )

Any protocol (ssh, ftp, sft, http, maybe via dhcp, ..), and any host key (HOSTNAME, MAC address, ...), and not even necessarily with DNS support - just to be independent from the OS currently running and able to make necessary changes immediately for the next reboot(s).
