twisted.spread is without a maintainer, and there were discussions in #twisted-dev about it's future. It has several flaws, mostly regarding security and resource usage that have not moved forward in a long time. These discussions mostly revolved around deprecating it, but Glyph pointed out existing uses of it and suggested looking for a maintainer first.
As such, we're looking for a maintainer who can dedicate themselves to maintaining twisted.spread and giving Perspective Broker a bit of love. This would require someone that uses twisted.spread, and is committed to its long-term success.
If nobody steps up, we'll declare it unmaintained and deprecate it in a future Twisted release.
