We might want to move OfflineWebApplicationCacheEnabled to an experimental disable feature flag. The flag should probably control exposure of ApplicationCache API.

Interestingly, Chrome disabled support for AppCache in non secure contexts at the end of 2019 (https://web.dev/appcache-removal/).

Chrome plan seems to fully remove AppCache support in H1 2021, which should give some information for regular browsing content and applications.
WKWebView applications situation might be more tricky to assess.

See bug 182442 for restricting to secure contexts.
