There is not really a "they".

This is a chicken and egg situation, since almost no one is working on
PDO, then it will be hard to get the patch reviewed and get karma to
commmit it.

If your patch is MS specific, maybe Pierre can help get it reviewed.
Join the IRC channel #php-dev-win on Freenode.net and ask about it.

In the long term, keep pestering folk about the patch and also
contribute more patches and suggestions/tests/doc etc.  This will let
people know how serious you are and how reliable your code is.
