No, I hadn't come across that option in my travels - that's useful!
Unfortunately it doesn't come back with anything:

$ stap -v -L 'kernel.statement("register_shrinker@*:*")'
Pass 1: parsed user script and 116 library scripts using 93372virt/31140res/3000shr/28456data kb, in 190usr/20sys/206real ms.
