I wanted to see how it would look if "whenever you zoom in enough that there's enough room on a visible street to put a label, then put the label!"
I think my render looks absolutely fine. I don't see why I wouldn't always use it if I had a toggle switch. Yes it's cluttered if you just glance at it, but we don't use maps as pieces of minimalist art.
You struggle to locate the names of the streets--in their absence, Google Maps shoves a bunch of unsolicited retail venues in your face.
Some people, among them apparently map makers, argue that "users don't want too many labels". logicallee is arguing that it's virtually impossible to put too many labels (by putting in as many labels as possible and showing that it's perfectly legible, and totally fine functionally, even if it's not the most aesthetic experience).
FWIW, I subscribe to OP, that it's infuriating not to have streets labeled, and find logicallee's point rather convincing, that having more labels doesn't really distract from the functionality of the map (and I don't care that it affects the map's "beauty").
Apart from being easy to consume, the map tiles must also be in sync with the company's brand and design ethos. Its hard to imagine Apple's minimalist aesthetic delivering these tiles.
