Re: WebAssembly a good fit for the future of GWT?

By "relatively easy" I still meant hard ;) Just easier than the other required parts.

I don't recognise your description of webasm. In the short term you have to use JS to load the webasm but after that you don't need JS again? GWT is even listed in their use cases http://webassembly.org/docs/use-cases/

In the future I'm not sure why my source Java would go via a JavaScript phase.

No, Java is HARD to execute. For example it is not possible to "unwind" or to walk the stack in WebASM, so java execution must maintain the second stack in order to unwind exception handlers. It is really hard to execute java in WebASM. Ask Alexey, the author of TeaVM. 

WebAsm is for "C", "C++" developers who want to write a JS function in "C".

The phlosofy of GWT is to write JS program using java syntax, which is very efficient in navigation and refactoring (where Js is not). 
This is a way to write JavaScript. And the direction of GWT 3 is good (JsInterop, e,t,c).
