TODO: Deprecate in favor of webextension-polyfill

[Gudahtt]

The webextension-polyfill project has similar goals to this project, and offers a nicer API. We should consider deprecating this project in favor of webextension-polyfill.

I'm not entirely sure the goals of the two projects are the same though, as they explicitly don't want to support non-standard features. If that's something we want, then maybe it's still worth maintaining this project.

Edit by @rekmarks: We are going to do this.

Here are the APIs detected by this package: https://github.com/MetaMask/extensionizer/blob/master/extension-instance.js#L1-L23
This is the list of Mozilla WebExtensions APIs: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API

As we can see, this package only detects a subset of all web extension APIs. We detect one Chrome-specific API, namely chrome.contextMenus, but do not appear to use it anywhere.

In the readme of this package, we also find the following line:

For the full list of supported methods, refer to the MDN API documentation.

Given all of the above, I don't think the intention of this package is to support non-standard features, and I think we can safely deprecate it in favor of webextension-polyfill. Perhaps @kumavis and @danfinlay have more context.

I don't think we've ever relied on any non-standard interfaces. It might be nice to use some at some point, though. I could imagine shipping some enhancements to browsers that support the context menu API. As long as there is a way for us to detect that later, it's not a big deal, it still seems better to me to use a commonly relied on module rather than continue supporting some thing that mostly only we rely on.

Possibly implementing this as part of MV3 work

@kumavis or @rekmarks would either of you be available to help me POC this. I'm having trouble getting this package to play nice with our build system.

Actually disregard my previous comment. I think I've got it figured!
