Right but this misses the point that you’re not removing complexity by shuffling it down a layer. Is it really an advantage to have multiple “thin browsers” if there are only two or three “browser engines” anyway due to their complexity? Further by pushing the complexity down a layer you inevitably make it slower. Aside from which from a market perspective most small browser projects already are a thin layer on top o…
