The webrequest stream, mobile webrequest stream, and zero webrequest stream
used to come with "mf-m=a", and "mf-m=b" markers in the X-Analytics field.
Now they no longer come with those markers.
However, it seems we need them markers to track usage of the
mobilefrontend for alpha/beta site.
(Diederik might know the details)
As there were some changes around handling of the X-Analytics field, and
around how the zero markers get set there, those changes of the puppet
repo might be related:

The markers seem to be set in includes/MobileContext.php:907 of
git:mediawiki/extensions/MobileFrontend.
The latest packets with those markers are:
