I know from my own experience that the 2,500 MQD headstart does not apply to new Reserve/Platinum cards issued after headstarts were added to people's accounts (I believe that was Feb 1). However, the new cards will get a 2,500 MQD headstart next year.
Also, I believe that you may have better luck when applying for a Delta AmEx Business Platinum card if you are eligible.
