Hello (and Pocket for what it's worth) are relatively small add-ons that ship with Firefox nowadays, the bulk of the actual magic for both happens in web content. Hello has a new tab-sharing feature, but that also works by sending media streams through WebRTC.

I am starting to suspect that their prominent placement and sudden appearance in the default Firefox UI caused people to think that they are taking a larger amount of Mozilla's development resources than is actually the case.

To bring it back on topic to Test Pilot - hopefully this will help the overall Firefox community vet these types of ideas before they make it to the default UI.

Even if the outcome is ultimately the same (new feature is added/default UI is changed, which makes some subset of people legitimately unhappy), it gives a wider audience a chance to test and provide feedback and generally socialize new ideas.
