Standardized web APIs are very rarely removed. Backwards compatibility is a huge priority for web APIs, and cases where they're broken are rare. It's very hard for me to even think of a web API like this that browsers have ever made incompatible changes to.
The parts of the web that get incompatible changes are generally stuff like nonstandard plugins (Flash being discontinued) and TLS (which isn't relevant if you're keeping some HTML file saved locally). Browsers bend over backwards to keep existing HTML/JS content working.
True, they are deprecated first.

That page supports my point! Most of the things in that list still work in browsers, and the few things that don't still work look like they're all things that never got standardized to begin with.
