Why jetbrain's MPS does not follow package structure for java classes

Question

I am just curious to know why jetbrain's MPS does not follow package structure for java classes. Even the editor available for java programs does not have a tag called package. Is there any specific reason?

Answer 1

You can create "virtual packages" in MPS: just select any file, open the context menu and select "set virtual package". They are mapped to Java packages.
