There may be someone using NVRAM for other purposes.
Actually, we have the user interface, /sys/firmware/efi/vars/new_vars, del_vars.

In this case, they want to avoid filling with unneeded logs.

In most case
But as Tony mentioned, NVRAM may be filled with multiple oops even if we have the daemon.
