@XhmikosR Are we still having issues with this? Caching etc? I'm not sure

4.1.2 release should be great, but it's more pain than it's worth it seems. We're going to remove it outright given how we're versioning and deploying docs right now.

I don't want to remove it, but it clearly is causing us more issues than I could imagine when we added it. And having a broken site is worse than not having the service worker at this point...

Do you still need help on this? I would like to possibly contribute.
