One of the beauty things about the currently alignment is it intercepts so many of the major streetcar lines, without destroying any of them. Also, the subway station with the most AM peak arrivals is Dundas, which at least is walkable from Queen station.I think it comes down to history here. For the DRL's entire existence the expectation was it would run along Queen Street to Roncessvalles at some point; so the extension down to the ex can be seen as a needless detour. Personally I have nothing against the line going to the ex but all things being equal if it were up to me I would have opted to cut that part west of Osgoode and divert its funding and resources to extending the line north to Sheppard. I would have also gone along King Street since prior to COVID the 504 was moving around 86,000 riders per day so its a prime candidate for a subway replacement (or supplement) like the Yonge and Bloor streetcars were.
Nothing precludes a future extension to Roncesvalles. In many subway systems, you see lots of bends, and even the occasional S bend, that seems crazy on a proportional map, but works just fine in operation.
