Another options will be to test a successful boot flag. (E.g. a touch
file in /boot/).
If the file doesn't exists (Post installation, new kernel, failed
boot/shutdown) grub should switch to a predefined timeout, giving the
user time to react.

The main issue here, is grub changes. Such a feature will require
changes to grub (code), kernel (post install script) and init functions.

While the last two are less problematic (bash scripts), given the fact
that development of grub is slowly shifting to grub2, I doubt that the
Fedora grub maintainers will be willing to spend time on such a feature
when grub is be phased out. (Or is it?)
