other clients to support all the features of Openfire
Which features do you mean? Fastpath maybe? Other than Fastpath there are no unique features of Openfire that only Spark can use. Yeah, there is also Client Management plugin, but that's a minor thing. You can use many other clients and still use Openfire, as Openfire is a standard xmpp server like the others.
Spark had many maintainers since ~2009, when Jive Software stopped working on it and released the source. But all of them found better stuff to do in their lives eventually Last one "left" around 2012-2013. Though there is no formal process for this. He just stopped working on it and nobody else stepped in his role. That's how open source projects are sometimes. Occasionally some volunteers provided patches and fixed bugs here and there. Last patch has been applied 1-2 months ago. So it is not completely dead, but things are moving slowly currently.
