There is no FreeTDS forum so this is the better place.
We miss even some feature of 3.5 (like *W functions) while you are
asking for a 3.8 feature :(
I was not even aware of this really interesting way of binding
parameters.
I don't think is too difficult to implement it but there is not even
plans for this feature (as the main ODBC FreeTDS developer and not
knowing this ODBC feature I can really confirm it :) )
