Monero_lover It is not a perfect measure but it could be possible to count the number of downloading for each updates.
Even this may not be straightforward. I believe the updater supports download resumption after an interrupted network connection.
Clearly, with enough time and effort an estimate could be made and posted. It would be fun to watch the number grow.
But I think the developers are pretty busy! I don't know if this would be the best use of their time.
