Installing a bouncer means following technical documentation and having a server free. The first requirement kills the interest of people who want a single app install. The second kills the interest of people who want the service free and run by a third party.

These are not enormous barriers but they were enough to put me off of setting up Quassel on a VPS for a few years. Now that I've done it I don't want to go back, of course, and I don't see it as a huge chore to do it again. But that's what's making it "not actionable" - the perception that this is going to end in a nightmare of configuration files and Stack Overflow searches.
