I'm fooling around. I'm sure everyone on the project rightfully will get a ton of return on their investment. I'm actually working on a browser UI myself. It's only because of platform OS integration that I'm using Java, but one thing I did learn using a lot of Kivy is how much of a pain it is to be far from the platform libraries.

Unlike Kivy, which is Python, you've chosen JS, so at least your UI is on a more naturally portable layer given that you have a browser runtime right there. Documenting your plumbing into the system libraries will be really critical. The JS community will hack every other piece of the system on their own, but user after user will shy away from the system plumbing because it's not what attracted them initially, so I would prioritize there.

Writing cross-platform UI's may be a pipe dream for now. OpenGL is headed towards a weird place with Mantle and Metal etc while OpenGL Next comes together. The HSA Alliance (Notably missing Nvidia and Intel) might offer some hope that CPU architectures and graphics API's (and GPGPU) will converge again, but right now, HTML5 with JS is probably the best we have for sheer everywhere.

Probably where I would diverge most sharply (and somewhat irreconcilably) with the web community and perhaps even the high-minded ideals of Mozilla is HTML/CSS, but the "superior" tools I find in Android are themselves relatively new. Do I wish that HTML/CSS/JS would go away? Yes, but without need of burial. A technology will displace it someday through sheer elegance that unicorns had not yet fathomed. If it's at all recognizable in what I'm using today, it's an early stage experiment.
