Have you read anything about this? What you are proposing is exactly what is being disabled.
Let's say that Google implements this restriction, but allows F-Droid a permanent permission to disable it for apps installed through their store. Then there is both increased protection and accountability.
edit: because the next step would be Google paying F-Droid a half-billion dollars for default search engine placement, or something else stupid. It becomes a captured organization, an excuse subsidiary.
