It seems to be a trend that is gaining popularity, and it is showing up in media as well. In the newest season of Ted Lasso, two characters share location while dating, and hijinks ensue when one turns it off.

I know some families who have enabled location sharing family-wide. It gives them a sense of security. I feel it invades my privacy, and so I do not mandate this for myself or anyone in my family, and would actively refuse to engage.

The ensuing argument is almost always "are you hiding something", but it's not that I have anything to hide (my location history would be quite boring, really), but just that I have an aversion to it entirely out of principle.

YMMV.
