They must be older than 10 cycles.
Is that new?
How did I know you were going to catch that?
It's like maybe a year old. I added it a while ago on a private fork when I was playing around with ways to limit explosive reproduction spiking CostX and well, it sort of "accidentially" made it into the main line. I've thought about removing it, but well, forgot it was there frankly. It has been removed in 2.43t.
