Leaving aside the opt-in/opt-out possibility.

You can remove the services that download the extra GPS data, nothing stops you from doing that, aside making GPS unusable :)

You have to manually strip the QCOM additions in the vendor side. It's just a matter of removing files, but I wouldn't expect to do it without some knowledge how the whole thing works in Android, without breaking GPS as a whole.
