I'm pretty sure nobody knew where Old Mill, St George, Summerhill and Bessarion were before they got built by this logic. They are just minor local streets. If you ask an occasion rider to point out where is Summerhill, I would say they are most likely to get it wrong unless they pass by it everyday or is a geek. Summerhill is also the neighbourhood of that area. So what can you do?
People will just learn that Mount Dennis is a major hub. Just like Kipling, Kennedy and Finch. Do it matter that Kipling is located at Kipling south of Dundas or Kennedy is at Eglinton east of Kennedy? Only if they are driving it them but you'll still need to look at a map to know that as it's Kennedy Station NOT Kennedy-Eglinton Station or Kipling-Dundas Station.
This really isn't an issue to non transit enthusiast.
