I agree with Gerry Danen. I posted a new comment instead of a reply because I don't think the article really explains what is wrong with the existing extension. Is there something inefficient about the existing extension. Is it inefficient or something. You explained why there was a good reason for changing from ereg to preg, but not what the case was for dropping mysql.

Since you didn't mention any existing drawbacks, I figured there were none, but it is good to see you confirm it. Is there any argument presented for dropping it (e.g. reducing bloating of PHP or something)? It seems to be a bad idea to me. Fix what needs fixing, but don't mess with what works without good reason.
