and you require a whole OS. I expect browsers to outlast OSes. Browsers ran on MacOS 9 and software that ran on those browsers still runs today. MacOS 9 itself, not so much
I've used a lot of old web applications which require some ancient web browser (especially IE) or old version of CGI or PHP to properly be hosted or require some browser plugin that is no longer supported. The idea that it'll continue to work just because it's "web" is once again absolutely hilarious to me. Just wait another five years and all the WebUSB protocols this relies on get reinvented and this gets considered unsafe and deprecated.
And sure, when talking about an OS that's often made a point at cutting off support for old binaries it's not good. You're ignoring the fact I can still run a lot of 30+ year old software on modern Linux and often modern Windows with ease.
