The push or step out rule is long over due. Here's the NCAA wrestling rules committee members - don't expect much from this crew:
Mark Branch, University of Wyoming
Kevin Jackson, Iowa State University
Matt Valenti, University of Pennsylvania Senior Associate Athletics Director
Jason Coomer, Southern Illinois University Edwardsville
Jason Warthan, University of Indianapolis Great Lakes Valley Conference AUG 2019
Lars Jensen, San Francisco State University
Brad Bruhn, State University of New York at Cortland Empire Collegiate Wrestling
Lonnie Morris, Johnson & Wales University (RI)
These are the current rules which are needlessly complicated and read exactly like they were written as a compromise by a weak-kneed committee members:
Rule 5.9.2
Each wrestler must attempt to work toward the center of the mat and continue wrestling in an attempt to secure a takedown, regardless of the time or score of the match. When wrestling is stopped in the neutral standing position for going out of bounds, one of the following three calls shall be made:a) stalling on one or both wrestlers for leaving the wrestling area; b) stalling for pushing or pulling the opponent out of bounds; or c) wrestling action is taking place.
Rule 5.9.2.5
Pushing or pulling the opponent out of bounds is stalling.
I'd just go with a step out rule in neutral position. The current rules allows the refs to do nothing, something they're very good at.
