It's not a done deal because:
- If we don't criticize what went wrong in the project planning process they will keep making the same mistakes in future projects
- Many of those things can still be fixed by additional investment. Like you said, the Line 2 upgrade was fairly cheap by Canadian standards and that's because they omitted so many useful upgrades. To the point that there are multiple items in the Ottawa Transportation Master Plan that are to fix up Line 2/4. Notably extending the second track through Walkley station to improve headways to 10 minutes and reduce travel times by a couple minutes. The best time to do that work would have been while the line was shut down, but since that didn't happen we should be talking about when we would like to go back and do it.
Yes! Those systems are even worse than Line 2! The Finch LRT is slower than the local bus it's replacing, despite having half as many stops and a dedicated ROW!
