Follow-up from "[EE] Snowplow - setUserId to User.id if available for gitlab.com"
The following discussion from !14182 should be addressed:
Have we instead considered adding this directly to the
Trackinginterface that's in
tracking.js? That way we can utilize some of the existing logic available to us in there and forego a couple of the checks here -- if snowplow tracking isn't enabled on the front end this can still execute as a tracking setup step.
