I don't expect Adobe to "start over," but how about improving existing workflows? I can't remember the last time I used "save for web" in Photoshop without then needing a second app to make the output file truly web-ready. I've not yet used CC 2015, but I assume SVG export from Illustrator still puts Adobe metadata cruft in the header? These are canary-in-the-coalmine features that could be improved so web designers at least get a sense Adobe is thinking about what they need in 2015.
