Related: Components: Remove "Experimental" designation

This issue tracks props that are pending stabilization in stable components. Stabilization, in this context, means the work required to stop using the __unstable or __experimental prefix, which can involve removing the prop altogether (e.g. reworking the associated feature in a way that doesn't require the prop) or simply renaming it without the prefix as a stable prop.

The reason why we still have experimental/unstable props in components that are considered stable is that we've decided that it was worth moving forward with stabilization of those components, without considering these props as blockers.
