FP4 Root Access is possible, maybe a bit risky

Thank. I ask because my previous android phone can relock after install magisk, and I believe many its user do so.

Therefore I tried to relock bootloader after root with magisk.

Did google change the policy?
Isn’t it dangerous to keep the bootloader unlocked?

I’m just complaining.
I read a post explain the relationship about unlock and security:

It seem we still had data partition encrypted before one unlock his android after boot.
