Bob, I'm not aware of that topic being considered for Division I baseball.
Obviously, Division I baseball has a 35-man roster limit. However in D2 and 3 baseball as well as other sports, they don't have restricted roster sizes so they're allowed to have freshman or JV teams if they choose to do so.
Two specific examples I've been made aware of are an Ivy League school that had a JV football team in the 2018 season and a JV basketball team this year at a D2 college that actually shows 56 players on the roster on their website!!
