Re better embeddability, sure. As best as I can tell the Firefox devs have been feeling some amount of dismay due to the fact that everyone embeds Chromium/Blink, despite the whole Mozilla/XUL thing having been built more as an application platform rather than as a foundation for one specific web browser. And that’s entirely understandable, as is attempting to do better on the second go-round. But now it seems that Servo is explicitly targeting embedding and -adjacent use cases
only, and that’s a post-Mozilla thing.
Re “safe”, I meant that targeting the embedding usecase is safer in a social and project-planning way, as in smaller probability of other people calling them nuts and greater probability of getting something usable in a finite amount of time. Which is fair enough.
