Primary key questions

How is the actual state of the support for tables with multiple keys? Is it in development or you don't have any plans for it at all? Because I've stumbled upon a case where this situation is necessary and gorma left me without much options besides changing the generated code.
Also, allowing a foreign key built from HasOne() or HasMany() to be the primary key also proved to be unfruitful. So what's the status of gorma about implementing this features.

Thank you in advance for your answer.
