A generic object model will be a poor fit for many languages. I hope they keep it simple and low level and don't build in an object model. I'd rather have low level features that let you implement your own GC than a built-in object model. If you have zero cost exceptions and multiple function entry points you can implement your own GC, and coroutines and various other constructs without any more overhead than if you were compiling directly to machine code. Basically, zero cost exceptions let you unwind and capture the stack while not slowing down the common case, and multiple entry points let you build the stack back up without compiling a large amount of duplicate code. This gives you arbitrary stack manipulation without explicit stack manipulation support in the VM. It enables features that usually require special VM features, such as GC, coroutines, lightweight threads, (delimited) continuations, effect handlers, C# style async.
