Please can you clarify your point? … implement what?
Many banks do not rely on Google “tricks”
Most builds are Community, that is really the standard and what I use as it happens.
The official builds are for phones which Murena sells or sold.
But I think your bigger decision is whether you want to degoogle. The idea of a perhaps cheaper second phone degoogled does allow you to get real time experience and you at least exclude Google from some of your networked activity, reducing the power of their knowledge of you.
