[racket] Swindle

Hello

I was looking for a CLOS(-like) implementation in Scheme and found that 
there is one which is already included in Racket. Before investing some 
time into studying this, I have 2 questions:

1) Given that the Swindle docs lack some polish in comparison with the 
rest of the modules, are they fully supported, as in "will they continue 
to be available in future versions of Racket"?

2) My (unqualified) first impression is that the OOP layer in Swindle is 
way more powerful than the "standard" OOP layer in Racket. Is there a 
reason why Swindle has not become the standard OOP layer in Racket?

Regards,
