Now, for those that say that is not enough for the legs, what you now do is make the Newton - Guildford section a new "line"
Build an extension north of Guildford to PoCo to connect with the Evergreen section. That would turn the Newton - Guldford section into the Millennium Line.
Then, a future extension to White Rock could be done.
Solves a lot of problems and gives more access to more areas by Skytrain.

Realisticly, you want the lines to be one so you can share the OMC's and rolling stock without having to operate them as separate systems. There is a tradeoff here where if the signalling fails for some reason, the entire system goes down, but that's a one in 5 year event. What fails more often are the switches, which is why the trains terminate at Edmonds or Columbia when the switch is stuck.
Anyways what I imagine is the main line Expo line going from Scott Road to Langley City Center, and then two "L" lines that extend from third platforms at Scott Road and/or Surrey City Center. The north L line Scott Road -> Guildford -> Langley. The south L line is then Surrey City Center -> Newton -> Cloverdale -> Langley. So each train that start or ends at Langley has the same frequency as the trains that arrive from Columbia.
If every third train goes to Surrey, then Surrey can have trains that do not cross to Columbia. So each side of the river has the same frequency, they just don't have every train cross.
If the Evergreen segment ever gets to Pitt Meadows, then it can also go south to Langley thus the main SoF hub is via Langley. It's too late to make any of the existing three stations the central hub since Surrey's existing stations were not built with multiple platforms (though I suppose there's nothing preventing one from being built at the cost of whatever is parallel to it.)
This is all just throwing darts at the wall though, one thing needs to be built, and whatever is built needs to have something like that built into it so that the lines aren't isolated (eg not like Broadway/Commercial) and thus if an additional OMC needs to be built, it can be built anywhere where the Skytrain tracks are. Those connections don't need to be actively switched (eg they could just switch tracks to adjust capacity, rather than run as a dozen different destinations.
Anyway, what I'm getting at the LRT fans (SBOT, and the developers) don't give a care where or what is actually built in the end, they just wanted to cash out as fast as possible. So if anything is built, it should be built with the intent of future-proofing the transit-oriented-development potential rather than just building whatever, wherever because property prices/development dictated the station location.
