Their CTR only extends to 2,000ft. Surely, if there's no cloud below 2,000 feet, you're better off asking for an IFR transit, else you're limiting yourself (and them) to all the constraints of an SVFR for little reason? If they want to send you up/out into the CTA, SVFR isn't going to be an option and you'd have to do it IFR/not at all anyway.
