- Lack of speed? - speed is equal to vue/react in dbmon benchmarks (even with polyfills).

- Tooling is quite good, polymer-cli, gulp, grunt support to name the most common stuff.

- https://www.webcomponents.org/elements - Thats a vibrant ecosystem :-) Big enterprises like ING, IBM, USAToday participate and release their components. (7k developers on slack channel)

- Insane data model? I work with my polymer elements same as I do with angular and react components. If in doubt just use redux/uniflow-polymer.

I get that you might not like it, but the issues you raised here are hardly valid (unless you used 0.5 or fresh 1.0)
