Hidden power pins are not the way to go! The fix for this bug must come from a different side then reintroducing hidden power pins.These pins can be visible instead of hidden, just visible power and common to all units.
How well defined is the behavior of kicad if multiple of these duplicated pins are connected to different nets? (Is the behavior what users would expect?)
And additionally: A schematic just looks bad if you have unconnected pins on some units. (How can a user explain these unconnected pins their boss?) Having the power pins as a separate unit is the way most other EDA tools go. This allows users to have power on a separate sheet and if the symbols are well defined one can even overlay the power unit with one of the other units. (Making this solution the most flexible option.)
That ERC does not check for non placed units is a drawback. As others already noticed most complex parts already suffer from this deficiency. (I am not prepared to make a hotfix on the symbol side to temporarily hide that deficiency in a limited subset of symbols.)
