There are several recovery disks available that could serve as examples.

This sounds interesting.
The only situation in which I would really have needed a "recovery
environment" was when after upgrading my old Fedora installs to Fedora
33 or something (whenever we switched GRUB to use BLS snippets, I
think) some required GRUB modules that were split off into subpackages
didn't get pulled in (I think it was grub2-efi-x64 ?), leaving the
system in an unbootable state, which I was only able to fix by booting
from a Live USB and installing the missing GRUB modules.
If I didn't know what to do (or wouldn't have had a Live USB at hand),
that would have basically bricked my system (or locked me into booting
Windows with its own bootloader). Not sure if it would be possible
with the "recovery environment" you would have in mind, but a basic
"are all the components that are required to boot there" check, with
suggestions how to fix them if they're missing, would have saved me
tons of time recovering from the borked grub install.
