It seems like a similar argument around the popularity of third party engines, whether studios should use Unreal, or whether they have the expertise/resources to change to and use another engine, or make their own bespoke engine, and if that will produce better results.

I think that is not fair comparison. Proton adds additional layer which can be completely removed and affects the runtime performance. Switching different game engine changes the layer implementation, instead of removing.
