I see that this is on the unconfirmed list of the bug report index. Verification is very simple.

Equip power armor with targeting hud.

fast travel to rocky cave in glowing sea.

save.

enter -- you will immediately become hostile, and if you have the quest for that location, you will fail it.

load your save.

unequip your power armor helmet with the mod.

Enter cave - turrets, et al will remain neutral.

There's even a mod that was released prior to 1.3.4.7 which dealt with this ('Simple Bug Fixes'). I had assumed that the bug was fixed and stopped using the mod. Pretty disappointed it wasn't, since if you don't know it's a bug, you'll miss all sorts of content when things go hostile to you for no real reason.
