In
crrev.com/c/3856942, the goal is to include prerendered pages in the UseCounter feature tracking. Currently, prerendered pages are excluded, meaning that feature usage on those pages is not recorded at all.
Pages may be speculatively prerendered, but then not activated, meaning the user never sees or interacts with the page. I'm wondering if a feature should be recorded as used, or ignored, in this scenario (
comment thread).
I don't know if we have data, or a prediction, to support an opinion. It could very well be that the volume of prerendered, not activated, pages never gets large enough to affect the metrics for any one feature. We could just pick an approach that seems reasonable (include or exclude), and not worry about it until there's evidence of significant impact.
Given UseCounter data is often used in compat decisions (especially deprecations), do the API owners have an opinion on this scenario?
Thanks,
Jason
