Good move in some ways but also this is now a massive problem because this wasn't something that was thought about until very very very late in the development/hypecycle of Discord, so now this is going to be a problem fraught with no easy answers because there are innumerable Discord communities that were created with never a thought to whether this was wanted or not and was never discussed by the community as a possibility until now probably.
The design choices or rather lack of proactive thinking about design here have put a huge amount of people in awkward positions in a way that was entirely unnecessary if Discord had embraced the idea of part of Discord communities being able (and even encouraged) to be searchable by Google.
