Improofe Performance with Auto render Layer

Render Layers are usefull but but its not always a quickand and easy workflow. May it be usefull to activate auto Render Laayering, so each Collection or each Object or each particle system... becomes its own render layer automaticaly, yes, Render will took longer but rendering large scenes would be easier and nobody have to decide what is in wich Layer. maybe adding a improofement with Patch like working, not only render the hole frame then, cause a lot would be empty , render only the relecant part with the speciffig object of that Layer.
