Very possibly.
> Supporting the use case you described, which is not used by the vast majority of users does not align with the incentives given to them.
I think you have causation wrong here. Users leave search history enabled because Google makes it unnecessarily hard to use the app with it disabled.
> Recently, Google updated its values (I can't find it externally but I hope you'll believe me). One of these values is "Respect the User".
I have no reason to disbelieve you.

If the values mean nothing without incentives, they aren't values, are they?
> You don't get a great performance rating for following the values, you get one for impacting some large percentage of users or improving the performance or conversion rates.
So what you're saying is "there's no incentive for allowing the user to have a good experience using the app without sending us data", or did I get that wrong? That doesn't sound awesome.
> Having users share location data, admittedly at the expense of privacy, provides a superior experience.
Especially when you don't bother providing a similar experience without people's data.
Ultimately, this isn't a question of "which would make Maps better, if users shared their data or if they didn't?". That's not your choice to make, so it's a question of "the user doesn't want to share their data, do we bother to make the experience good for them or not?"
If your answer to the latter is "No", I don't care if your values say "The User is the Alpha and the Omega, thou shalt have no other priorities before the User", it's a red herring because you aren't following your values, you're following the money.
