Still makes it hard for people using different arches to run around looking into various DATE/ folders to see exactly which of them has the latest armv7, landisk or octeon release which will not be published daily for L2 mirrors to sync. Whatever the solution is, it needs to handle 100G large snapshot dirs partly updating daily, partly updating every 30 days. It's not just "buy an extra drive for the server". -- May the most significant bit of your life be positive.
