I just want to say how excited I am by this and also you should definitely look at supporting yew as part of the work. The elm architecture is something to be emulated, and yew is already coming through as an extremely usable web framework.
I’m already in two WG so I won’t be able to be part of this one, but I wanted to make sure yew got some love 
Edit: heads up that I am currently rewriting artifact in yew and plan to port the backend from Nickel to Gotham. Hopefully I’ll have rust as an end-to-end modern web+cli application up in no time
