Not sure what you mean by "without the benefit of expandability"? How is it not expandable?

Absolutely, but what I was trying to point out with regards to "preference" is that people prioritize and attribute different levels of importance to different things, and that is what a lot of it comes down to.
I think it's important to provide the best connectivity and level of reliability possible to serve us better further into the future, and I think a tunnel does that best because it provides more seamless connectivity, minimizes the potential for service disruptions and ensures we have a piece of infrastructure that can handle greater capacity much further into the future. If there's any segment of the tram line you want to futureproof the most, it's this section, as it will be used by all of Gatineau's future lines well into the future.
Look at all the examples where even planners thought that a certain configuration would be "good enough" only to have it fail spectacularly. Like the Trillium line for instance. We spent millions on bootleg upgrades thinking it would provide a great benefit (8 minute frequencies) at minimal cost and we end up with barely any benefit at all. Edmonton thought it could get away with a signalized level crossing on the Metro Line downtown, and that failed spectacularly as well. I'm sure if you ask many, including professionals, they would've endorsed more spending for those extra upgrades in retrospect.
I find we often overestimate the LOS achievable with cost-cutting alternatives in this country and underestimate the ROI of higher quality, more costly designs.
