I realize this is common; however, I just looked at the build number on my wife's old VZW Pixel 3, and the build number is identical to the latest public version available on Google's site. So it does not appear that Verizon is using private firmware. Bootloader version is the same, too. So if those components are the same, what else would prevent bootloader unlock?If you are saying flashing the VZ version or taking a VZ OTA on a Google unlocked phone will prevent you from unlocking the phone, that is incorrect. That isn't the case now, and has never been the case on the previous Pixels. The only difference in the image is the modem. In the next month or two you will see the different versions merge into one. These temporary splits in versions are common. Look at the factory image versions for the Pixel 5 and you will see this.
