• explore race condition at endStudy (see Kamyar, TAAR)
• rename / simplify ping sending (sendEnterPing and friends)
• require variation for setup to eliminate setVariation
• logging
• handle normandy uninstall as a special thing

Suggestion regarding logging: implement it in the same way as pioneerUtils: https://github.com/mozilla/pioneer-utils/blob/master/src/PioneerUtils.ts#L306

Suggestion: Target v5 instead of 4.2
