Small observation in case it’s useful: a month after it switched itself on here, markdown-endpoint:cooked:* was about a million keys, 87% of our Redis keyspace (~570 MB). Nearly all of it from bots fetching .md pages, each post cached for a week. It just seems like a lot of Redis for one feature.
Which makes me curious about the other side. Has anyone seen real visitors come back from it? That would make it an easy call to switch back on.
