Sorry but this will very likely never happen unless you do it yourself together with other interested people and manage it on Github as a community project. Google (GWT's main committer) invests in J2CL + Closure Compiler in the future so they won't do it and current contributors will likely favor SDM and don't want to manage a custom chrome build (at least that is my impression).
I think you never really dived into SuperDevMode. Take GWT 2.8, start SDM with -style PRETTY and disable sourcemaps in Chrome to see the real JS. Now search for any method name and take a look how GWT sets up classes and methods in JS. Once you understand that (really easy to understand the basics) you can easily find what you are interested in, use watch expressions and set conditional break points. You can also hover variables to see their content if you do not use sourcemaps. Given that GWT doesn't really optimize the JS code all the Java methods in your project will look pretty similar in JS. If J2CL plays out nicely and GWT 3 will be build around it, then the generated JS will likely even more look like Java as it will use ES6 JavaScript classes. So the need for sourcemaps (and its disadvantages) during development will be questionable. DevMode had its time, I never really missed it. It's slower than SDM, you can not use it do develop directly on mobile devices (granted with SDM and a certain app size its also not possible because the SDM JS is so large that it crashes the mobile browser), DevMode had executed Java code in JVM which sometimes had different behavior than the compiled JS which could lead to bugs in production you can't reproduce in development unless you compile your app. IMHO SuperDevMode is superior to DevMode once you make yourself comfortable with Chrome and its DevTools. The only sad thing is that SDM still has some hard to reproduce bugs that every now and then show up during development which require you to cleanup the cache and start fresh. -- J. -- You received this message because you are subscribed to the Google Groups "GWT Contributors" group.
