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?

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.
