Is there any reason why HABTM default select clause is select *  
from ... rather than select table_name.* ... ?
As it is attributes from the join table 'leak' into the attributes for  
the collection you are fetching (which for example makes a mess if you  
call to_xml on it). On the other hand has many through does do select  
table_name.*

Is there a specific legacy reason why this is so or is it just  
historical artificat (ie can we just change it to table_name.*)
