I agree, and I'd like to see a unified way of connecting to those services. These services are in a way plugins, so I could see it being handled by having a plugin framework that's capable of handling in-app plugins via something like ZeroMQ, as well as external plugins (remote services or from other apps) via something like Matrix. Essentially, a key part of the idea is to create an Open Source project that is a browser construction kit rather than a browser. Then anyone can choose what components they use. Big brands can release branded sets of components that include proprietary components if they want - but users won't need to use those to have a safe, secure, and rich browsing experience.
