Next steps: check mpic configuration options and update ticket based on what's already possible

The Measurement plan doesn't call out a specific sampling rate (yet), do we know what it is?
Is the actual device being captured to determine if it's really mobile, or are we just basing it off the skin?

Currently, it's possible to use the Minerva skin while logged out on mobile because https://en.wikipedia.org/wiki/Main_Page redirects to https://en.m.wikipedia.org/wiki/Main_Page. I'm not sure if this will still be possible after the removal of the mobile domain T402880: Spike [1hr] Investigate impact on Readers Growth team of mobile domain removal in WikimediaEvents schemas.

Initial experiment has already been configured on MPIC

Wikis and sampling rate are explicitly set here, while logged-out users should be implicitly configured via User Identifier Type: edge-unique.
The skin check is implemented in T404233: Image Browsing: Gate the feature properly (patch) instead.
