New description:

 So far we've been lucky that the npm modules we've been using are
 available through Firefox and Chrome APIs. That's not the case for
 [https://www.npmjs.com/package/stun stun], which we need for #34129.

 ~~It looks like there are some options for packing node modules for use in
 web applications: https://www.npmjs.com/package/webpack~~

 ~~But we might need to modify our build scripts.~~

 Now it seems like we'd have to implement our own STUN library from scratch
 using the UDP socket APIs.

 It's questionable how worth it this is at the moment.
