I don't think so, & opposition didn't play as big a role as people think. The reason Metro sucked until fairly recently is it was designed primarily to get suburbanites to work. DC residents & recreation weren't really considered. That's why it stopped at midnight.
When the stations were being planned, Georgetown didn't really have a lot of workers or big workplaces. If it had, the rich people probably could not have stopped it. Metro wants to build a second tunnel to ease the Rosslyn bottleneck, Georgetown would get a station then.
