I’d really like to see omniswitch on /e/, because it’s a great feature.

Do a search for OmniSwitch in the forum. Mentioned in the past but I seriously doubt it’ll ever happen. Heck, even crDroid, which included it for ages, got rid of it.
no it isn’t:
Those are all old versions, see here: android/omni-private.xml at android-13.0 · omnirom/android · GitHub
The changes are uploaded to gerrit.omnirom.org, so they can be pulled. I am pretty sure the omniswitch is licensed under the GPL so the newest version has to be open source.
