You didn't created Emacs 20-mode when you switched from Emacs 19 to Emacs 20. Why should you have new mode for new version?
I don't think this entire discussion is about being modern, but about being more like other software.
As I have followed original Andrea's proposal, here is what I think:
Make a list of external packages that are legally and technically acceptable for inclusion in Emacs (for example which-key)
Include those and enable them as default, not as a mode. Old users are experienced enough to setq a variable or two, or change it via customize, new users are not.
Rarionale: you already have such features (me nus, tool ars, scrollbars etc) that experienced users usually turn off. Same is with which-key and other new packages you choose to include.
Keyboard interaction is another subject in this "modern" discussion. 3d modellers/animation packages usually come with key-bindings that resemble competitions package. That to make eventual transition easy. I have no idea if it is fully possible
in Emacs, but Emacs already have Vi emulation. Maybe there could be VisualStudio too (or whatever is interesting)? Remapping C-x & co is probably not directly trivial.
Looks: Emacs has themes, and there are quality themes out there. A not so trivial part is 3rd party packages which has to be skinned "manually", something seems to be missing, so complete theming framework so 3rd party packages can also get
blended into looks automatically (a thread about color scheming is about that).
