No way to change preMajor spec parameter

I've noticed that when in 0.y.z version any commit is treated as a patch. I did some research and couldn't find a reason backing that. When I wanted to overrule this I saw that my config is ignored and preMajor is set to true regardless. Why and can we be allowed to change it?
