I'm pretty keen on the whole plugin idea, because it makes the compiler more extensible and lowers the barrier to entry. My only reason for delay is that I wanted to review the design (as seen by a plug-in author). Once we provide it, we have to support it, and it's harder to change.
The Scala compiler has a plugin system. Here's a document that describes their approach to dealing with phase ordering of plugins: http://www.scala-lang.org/sid/2. It seems rather complex, but seems necessary (or the document is just very long). There's also a tutorial on writing Scala plugins, which may help to get a feel for how their API works. http://www.scala-lang.org/node/140 / Thomas
