Performance graphs
Alice suggested that instead of asking for the graph links to be maintained, I could instead file bugs for making the graph server not suck so much that we need the graph links. I filed four bugs, but I'm not one of the main consumers of performance graphs, so it would be good for actual developers and sheriffs to weigh in.
What use cases are important and not covered well by the (new) graph server, johnath's performance dashboard, and the automated posts to mozilla.dev.tree-management? What would help us notice and track down performance regressions quickly?
