They're not lost opportunities, they're scrapped ones.
Leftover dialogue, markers, quest updates, and other evidence suggests that at one time the game's developers intended the Civil War to be much more dynamic and complex than it currently is. Taking a hold would have involved capturing the outlying villages and/or points of interest as well as completing the regular missions. In addition, sieges like those seen during http://www.uesp.net/wiki/Skyrim:Battle_for_Whiterun_(Stormcloaks) and the final two battles were intended to occur with each hold capture. On top of this, the opposing side would actively participate in the war, which would have forced players to play defensive as well as offensive missions. Finally, it would have been possible for the opposing side to lose their main capital yet still have other holds, meaning the final battle may have taken place elsewhere (for example, for the Stormcloaks the final battle could also have taken place in Markarth, as well as Solitude.)
