I don't think that I've ever seen an Imperial AI use the Imperial Liberation CB. In fact, I don't think I ever saw it used in EU3 either.
In EU3 this wasn't a huge biggie. In EU4--with HRE members spamming the conquest CB all over the place--its more of an issue. It is, I think, a major contributing factor leading to the manner in which the HRE coalesces fairly quickly into a relatively few large(ish) states.
I just wanna send a diplomate to Austria "Are you seriously just gonna let Bavaria get away with that shit AGAIN?!"
