CNAME+A record in response

A lot of times we get responses that look like:


BIND currently (atleast with the default settings) when it encounters
a CNAME stops processing and checks if EXAMPLE.BAR is in cache or else
sends out another query to resolve it even though the A record in the
packet completes the chain.

Now, is there a setting in BIND to accept the A record or do providers
and ISPs keep adding these information in the hope that some resolver
might use it ? If there is a setting in BIND to accept it, what is it
and does it only work if the label and the alias of the CNAME are in
the same zone.

Help is much appreciated.
