Flash was not part of the web platform. It was a plugin, a plugin that was, over time, abandoned by its maker. FTP was not part of the web platform. It was a separate protocol that some browsers just happened to include a handler for. If you have an FTP client, you can still open FTP links just fine. Non-HTTPS sites are being discouraged, but still work fine, and can reasonably be expected to continue to work indefinitely, though they are likely to be discouraged a bit harder over time. XSLT is part of the web platform. And removing it breaks various things.
