Yes it’s great people use it and report issues. I found and reported a years old bug in Erlang that was exposed by a zlib update. Arch makes it easy to isolate and rollback dependencies which was helpful to isolate the change. On the other hand, Debian/RHEL users never had to know about this complete showstopper bug since they never ran a system that had the new zlib and the old Erlang at the same time.
