Class-based dynamic languages on Truffle OSM

I recently read the very interesting Truffle OSM paper
If my understanding is correct, the paper proposes to treat all guest
language (g-lang) objects as instances of a *single* Java subclass of
StorageObject, like the exemplar JSObject.
While this one-size-fits-all approach might be ideal for prototype-based
or open-ended class-based g-langs, where instances can grow as new
properties are added at runtime, I wonder if it is ideal for those
dynamic g-langs where the set of instance variables (fields) is fixed at
class definition time, like in Smalltalk.
I'm not sure if my understanding is correct or if Truffle/Graal's magic
is able to optimize the size and the shape of objects along their way
from birth to death. This would be wonderful!
Any clarifications, even technically detailed ones, would be welcome.
Thanks in advance
