Non-CL backends, like contribs, are maintained by whoever feels like
it. There's no "official support". I wouldn't mind distributing a swank
backend for clojure within the contrib/ directory -- but, personally, I
wouldn't have bothered checking its workingness back then even if such a
backend had been available in the official distribution.

The API for SWANK:ARGLIST-FOR-ECHO-AREA changed; I do not know why that
change triggers an infinite loop in the respective clojure code. My
hands are tied on this issue -- report to the maintainers of the clojure
fork that this portion of the API changed. The new API is described in a
comment in swank-arglists.lisp. (The upshot is that the new API allows
for more fined-grained highlighting of parameters in case Clojure has
something like &key parameters.)
