OK so you're saying when the user chooses, from the ISOLINUX based menu:  Troubleshooting > Install Fedora in basic graphics mode, that somehow anaconda knows this was selected. As far as I know, the only preservation of this selection that anaconda has access to is 'cat /proc/cmdline' to reveal 'nomodeset quiet' was chosen. But in such case you want grub2-mkconfig to contain another entry (ala Recovery Mode entries).

Anaconda doesn't create the grub.cfg, fyi. It directly calls grub2-mkconfig to create it. So the feature you need would be anaconda getting and parsing /proc/cmdline/ and then feeding an option to grub2-mkconfig, possibly via /etc/default/grub. So the feature ultimately is both an anaconda and grub2 request.

(Honestly it would be helpful if the basic graphics mode selection deleted quiet. The option is being chosen to deal with video related problems on boot, seeing as much information as possible on screen the better.)
