The same is happening in the Computer Security academic research realm. All of the four top conferences (USENIX Security, ACM CCS, IEEE S&P, and NDSS) have instituted a submission cap--you can't have your name on more than 6 papers being submitted in a given cycle. This has all happened within the last year, likely due to the same GenAI abuse that puts undue burden on PC reviewers.
Having been on the program committee for some of these conferences, this issue of limiting number of submissions was being discussed long before GenAI. Specifically, there was talk of a few highly prolific security researchers that submitted 15-20 papers to these conferences each cycle, with pretty good quality too.
