I do not think it would be very fair, because low-end systems are less likely to
run popularity-contest than more recent systems, so the fact that none of them are
running popularity-contest would not imply that there are none.

This issue has been discussed in the past. I have no objection for popcon to
report sub-architecture and/or CPU *provided* there is a canonical/official
way to retrieve this information from a Debian system (e.g. an hypothetical
dpkg --print-subarchitecture) that work consistently on linux/kfreebsd/hurd.
Imagine a large red swirl here.
