Ok, I meant the same thing. So, the answer you already have - not planned
unless somebody contribute right solution.

Pragmatic reason from the driver developer's point of view is quite simple -
very likely you need to write full-fledged SQL grammar parser. Then you have
to code a way how to fill BLOBs via statements (currently not possible in
Firebird). But the worst thing is that you might need to update parser with
server changes in the SQL. And it is not job of the driver to parse the
SQL - that is job of the database engine.

And from the application developers point of view your unwillingness to
introduce new method to handle prepared statements you are going to slow
your application down at least twice (most likely more). Very unwise.
