>Security implications are.. no security
I just spent about 20 minutes searching trying to figure out if my encrypted phone can somehow be unencrypted because I have an unlocked bootloader. I couldn't really find a solid answer. I guess that would take some NSA level skills and not something a random person stealing my phone would be able to do.
I did find this guide to locking my bootloader:

However, it just doesn't seem worth the time and risk of bricking at the moment. Definitely a big plus for Graphene for supporting this with ease.

I have a long pin lock + encryption and no root. I am not really worried about someone flashing malware on my phone via physical access. Either way. I think it's a large step up from the situation I was in before.
