[Frédéric Wang]

Hi,


As of september 24, I intend to disable the features below on all
platforms. For details, please read the intent to deprecation threads
linked below. We have sent deprecation warnings for them since last year.

Emilio helped me to collect the data and the number of pings with
such counters (collected on the release channel on data submitted from
early-this-august) are litterally 0 or 1. As a comparison, the counter
for pages using MathML is in the millions.
