FRP means nothing either once you unlock the bootloader. So, if your endgame is solely to protect a person’s information and their thousand dollar device is secondary to that, I guess that’s a win? Personally, I would rather hold onto both, but that’s just me.

It isn't in scope for us to add FRP currently since it won't guarantee you will get your device back if it was stolen. We haven't implemented it since it could also be a problem that the data forever remains in that device, at least we can encourage whoever has it to inadvertently destroy all the data.
We also had a lot of concerns by users about Find My Device functionality as some users consider being pinged by other phones to help location tracking a huge privacy issue. Both FRP and this would have to be opt-in features.
