Discord is the most prevalent and lowest friction communication app for the highest portion of the relevant audience, and will only become more so with every new (younger) developer cohort.
The average 16-34ish year-old probably-male developer that owns a PC with a discrete GPU almost certainly already has Discord installed, and does not perceive any undue burden from being "forced" to use an app they already use regularly, for better or worse: https://www.statista.com/statistics/1327674/discord-user-age...
In my opinion, the best solution is Discord getting ahead of this and letting admins make in-server threads visible to the clearnet.
