I noticed this change.
It turns out that
/etc/default/grub - contains default kernel options
/boot/grub2/grubenv - has the entry saved_entry=<id>
which refers to /boot/loader/entries/<id>.conf
which contains kernel options for the entry (which are actually used)
which get modified when editing kernel options via grub menu (thus
becoming persistent)
Also
/etc/default/grub - contains GRUB_ENABLE_BLSCFG=true
which is documented at
https://fedoraproject.org/wiki/Changes/BootLoaderSpecByDefault
