3 is completly untrue

until now after kernel updates grubby is adding the new one to grub config
and taking any chnage you made in the previous one to the new entry

only "grub2-mkconfig" is creating a complete new config
with all this submenu crap and so on
for kernel params "/etc/default/grub" is your friend here
