Quick release and a bag is quite a good one.
Not many bikes with no saddles get stolen to boot.
I've seen (from your shop), at least 2 track frames with cracks on the seatpost area due to seatpost QR. IMHO it is a really bad idea, on a track bike people have the wrong idea to tighten everything too much, it will very rapidly weaken any frame, and QR clamps on a everyday basis might be pushing it too far.
