This doesn't seem any better, or worse, than any other similar 
exploits; if you allow improvement rolls for trivial uses of skill, 
what's to prevent someone from advancing in them for _shooting_ at the rats?

Just like anything else, POW checks need to be applied only when the 
use was meaningful; if that's not used as a criterion, the whole 
system falls apart.
