It's cool to see the work on Servo since Igalia picked it up. There was a lot of tech debt to work through due to years of minimal maintenance, but they seem to have been making real progress.

My personal hope is they push hard on the modularity angle. Seems to me that:

1) there's probably a niche to be filled by an OSS browser engine focussed on embedability

and

2) That it could be a huge boon for the long-term health of the web platform if there are build-your-own-browser "lego building block" libraries that people can mix and match to create new engines.
