Thanks, Sam. Nuria, that's what I was getting at -
if using the EL JS
library would some sort of new method be needed so that these
impressions
arena't undercounted?
If we had a lot of users with DNT, maybe, from our tests when we enabled
that on EL this is not the case. Your team has already run experiments on
this functionality and they can speak as to the projection of numbers.

Adding to this, one thing to consider is DNT - is
there a way to invoke
EL so that such traffic is appropriately imputed or something?
The EventLogging client respects DNT [0]. When the user enables DNT,
mw.eventLog.logEvent is a NOP.
I don't see any mention of DNT in the Varnish VCLs around the the /beacon
endpoint or otherwise but it may be handled elsewhere. While it's unlikely,
there's nothing stopping a client sending a well-formatted request to the
/beacon/event endpoint directly [1], ignoring the user's choice.
