E.g. I cant store my home location in Google Maps without turning on Web & App activity history. Why? I cant share my current location (not historic, just my latest location - they only need to store one) with my partner unless I turn on Web and Location history. Why?
I am sure a lot of people will now pipe-up and say "Ah well they want your data! That is why!". Kthx bai for that - I get it.
It strikes me as this being a "nudge" more than anything, or perhaps just a cut-corner to get a feature enabled rather than support something custom (e.g. in the case of my current location vs location history, it was probably easier for them to build something that just picks the most-recent record off of the top of your location history rather than create something new for only storing the most recent ping independently from location history along with all the privacy controls, legal reviews, documentation, and UI fiddly bits that go along with supporting something new)
