(not sure about Templeton and Sea Island, but since both of these are ground level, it's not a problem) The rest of the underground stations have the 10m reserved, covered by a faux wall, but they are unfinished. The other elevated stations may pose more of a challenge, particularly Bridgeport imo. Bridgeport is sandwiched between 2 switches and it's going to be super tight fit.
Imo, even at 50m the platforms are still not long enough. They should be 60m, at least. However, given that most stations only has 1 flight of stairs and 1 up escalator, I wonder if the stations can even handle the extra foot traffic. Brighouse is already packed during rush hour and that has both up and down escalators.

They can do whatever they want if enough money is thrown at it since it's grade separated. If they want to extend the platforms to 200 meters they can, they just have to mine out 140 meters in the underground segments and rebuild the tracks. It doesn't make economic sense to do so, but they can. It makes more sense to actually build a parallel track (eg down Arbutus) to provide relief to the Canada Line when the time comes. The knock-out panels provide for extending the platform lenght to the maximum design. There is still the question of train capacity. Like the actual Skytrain system, it's probably capable of one train every 75 seconds, but where are all those extra trains going to be stored?
Compared to on-street LRT/Street car options where you can't extend the platform because the train will block the intersection. They are decidedly set at the length of the smallest at-grade block length, otherwise they have to close the intersections permanently.
The most likely scenario is that when the Millenium Line is extend to Arbutus, there will be a proposal to turn the Arbutus corridor into another subway to retain the "bike trail" that the surface will ultimately end up as. That will end up going from Grandville Island down Arbutus to Marpole and cross over at Cambie. Then the next Subway ends up being 41st or 49th. It's more likely there will be a Hastings line before there will ever be an Arbutus line.
But more to the point, we are lacking in north-south connections. A Clark/Knight Street would connect everything from a Hastings, Millennium Line all the way down to a possible second crossing into Richmond. The other possibility is through Burnaby down Willingdon to Metrotown and then down Sussex maybe to Big Bend (though not likely since the grade is super-steep once you get to Rumble.)
