So giving Google my location history so I can also give them my credit card numbers when they don't need those either is not considered a feature.
I use Google Maps frequently and have been bothered by any behavior changes there. My home address auto-completes easily enough and in some contexts Google clearly does seem to know my "Home" address (which I'd tell them if they just asked if they didn't want my lifetime location history along with it).
If I save a credit card on my iPhone it saves that information to all of my iOS devices, and all of my Macs automatically. Even devices going back to 2012.
There has been something seriously fucked with Google Maps in this particular regard. On my phone with my location/privacy settings, it takes Google Maps 5-10x times as long to get a location fix as it takes OSMAnd. It works eventually, but it's dog slow.
