No, it's a sign that it's not that complex.
You can't? Am I to assume that you've run matrix analysis of all plausible chainring/cassette cog combinations, even if those combinations don't fit within the status quo dictated by current hardware and user shifting limitations? I'm sure that Shimano would be interested to look at your work.
Oh, now we're completely redesigning bicycles? I thought we were discussing next gen of Di2, not changing chains, chainrings, cassettes, frame spacing, and everything else. That's a whole different animal.
Incorrect - some of us KNOW that shifting is currently a compromise because of hardware and user limitations. It can be made more efficient.
Everything's a compromise. The worst parts of today's indexed mechanical shifting (non-linearity/drift of cable tensions, FD trim, and front shift speed) are neatly addressed by Di2. My biggest wish for future versions is frame integration.
