Definitely rarer these days and even more difficult for a non VIP to get since they can be offered to VIPs as an additional bonus since they don’t count against their two quota bag annual limit.
I've found this to be true with the Pochette and the Kelly Cut. Any KC I've ever been offered have been as a bonus "add on" as a little surprise when I've picked up a QB from my SA, and then any Pochette I've been offered, same deal. I have, however, turned down all KP offers because I don't care for the style, oddly enough.
