They don’t unfortunately but it is a good reference for me to check how it looks on previous versions of browsers and less powerful devices. That way I know if the UI or UX needs improvement.

ios updates unfortunately ties everything to a single batch. Unlike android. I have an older blackberry, that still gets latest app updates.

What is even hilarious is ads render with pixel perfection on older devices. So for some reason, ad networks care about browser compatibility than devs putting the same ads on their incompatible website.
