I think we should revisit this. If users are following our recommendations then they’ll be running the latest Android anyway. It looks like A15 adoption is now at around 30%. When you take into account that a lot of Android devices are smart TVs and the like that don’t get regular version updates, I think it’s fair to say enough users are on A15 that we can remove shelter now.
Also it seems like Shelter hasn’t had an update in around a year which is a bit concerning.
