I agree it doesn't make sense for Servo to be a drop-in replacement for Gecko, but that doesn't mean we shouldn't bend Firefox towards compatibility with Servo. A future Servo-based Firefox is far enough off that it's impossible to predict every step from here to there, but if you ask me, dcamp's email is on the right track: we should evolve Firefox away from dependence on non-standard tech like XUL, XBL, and XPCOM and towards self-hosting on standard web technology and taking full advantage of everything Servo has to offer. What that looks like in practice remains to be seen.

I agree. A key point to achieve that is to define what the embedding api looks like. Right now on FirefoxOS it's partly the mozbrowser api for iframe-centric features, and partly custom events that are dispatched on the top level "chrome" iframe. There's still some cleanup to do there ;)

Of course. I'm just saying that from the point of view of Servo, drop-in Gecko isn't really the focus. Making Gecko more HTML-y is a great step for Gecko, but from a purely Servo point of view at the moment it's not really something tangible. Though you're right, it may mean something for Servo a couple of years from now.
