See https://github.com/ppy/osu/actions/runs/13623586844/job/38143232417?pr=32180 for one example. Arguably the bindable usage in [`ControlPointPart`](https://github.com/ppy/osu/blob/2365b065a4994f38fe67bab7d193e5a09bee538c/osu.Game/Screens/Edit/Components/Timelines/Summary/Parts/ControlPointPart.cs#L24-L26) is dangerous, but it's only dangerous in tests (because control points aren't mutated outside the editor) so I'm willing to turn a blind eye for now to favour async loading support.
