That's been the case for a long time and it works well. Already that will introduce some slightly interesting shapes in the network graph as not all instances will have matching blocklists, even though the reasons for blocks right now are similar. It's also not a black and white action - instances can be blocked completely, or just limited (blocking files & attachments or post visibility without blocking user follows, etc.). However I'm curious to see as the network gets a lot larger whether that network graph shape gets a lot more complex as certain instances start blocking others for a broader variety of reasons. For example I've seen discussions of blocking sources news/journalistic content on an instance intended for friendly community chat. I think it'll be interesting to observe what bespoke & unique moderation policies emerge.
