This isn't just to "please Canonical." Like I said, please read the specs, having a _consistant_ way to do indicators is a win for users, I'll copy them here:

Application indicators are more consistent – no more left and right-click inconsistency.
IMHO, different behavior for different mouse buttons doesn't feel like inconsistency. Feels more like "functionality". Left click to reveal app, right click for menu. You don't even need to remove functionality to make it work on tablets. You can map right click to long press or double tap. Slide down from tray icon gesture would work even better.

Anyway, I strongly prefer inconsistent tray icon to not existent tray icon.
