Context
During T122504, I found that we log MobileOptionsTracking events whenever a user updates their mobile preferences and asked Readers-Web-Backlog whether such logging was valuable, to which the answer was "Yes." @Jdlrobson noted that we also log mobile preference updates with calls to wfIncrStats but this should have been superseded by the aforementioned event logging.
AC
- All calls to wfIncrStats are removed from the Special:MobileOptions code
- An email is sent to wikitech-l, mobile-l, and reading-wmf with details of the forthcoming change
TBD
- The statistics gathered via wfIncrStats are purged
