The problem is that ev_prepare watchers have a special purpose and special
semantics - you can't do everything inside one. While you can make a hack
that calls newly-added prepare watchers, the awkwardness, as you call it,
remains (a prepare watcher callback *has* to be aware that is is a prepare
callback, it's not a normal callback), but the rules have become more
complex, which is a loss-loss situation to me.
I think chances are high that you are using ev_prepare watchers for
something they were not meant for (integrating other event sources), and
likely, the awkwardness will go away once you stop doing that.
