I have no idea where in the docs you found that, but if it's really
there, it is a documentation bug. Prefetching has_many relationships
has been working at least since 0.06000 (I think), probably earlier.
Also, in DBIx::Class::Relationship docs there's even an example of it
being used.

Finally, just in case there were some known issues with more than one
level has_many rels beeing prefetched, I actually asked mst yesterday
on IRC and he said it should be working alright.
