Re [0], note that Google Maps on the other hand seems to handle lack of JS very well. I guess it can be blamed on different teams in the same big company.
If by "seems to handle lack of JS very well" you mean "does not work at all", that makes sense. Not being sarcastic either, it seems they decided to take an all or nothing approach and force the user to enable JS to use Google Maps, or instead see this page: https://i.imgur.com/Qc156Ds.png
Maybe the maps product wholly depends on JS for all functionality?
Yeah, my point is that they put actual effort to show you a nice-looking page when viewing Maps without JS enabled. Compare to the Chrome download page, which blanks out. This is orthogonal to whether or not a service can/should work without JS enabled.
