Re: scout ball.
Scout teams are (or were during our time) made up of the best of the best of the local HS players. The overwhelming majority of the older players are committed (no surprise there). There is minimal coaching, an informal atmosphere, scores are not usually kept, there may or may not be umps, opposing teams are often from JUCOs, and there are no practices. The stands are filled with scouts and college coaches (looking for the few sophomores). The cost is nominal (we paid less than $100 for the season). Attendance at games isn't mandatory as testing and football also exist.
Pitchers will throw an inning or two and games will last often as long as either team has arms. (We drove 3 hours to his first scout game and he threw a dozen pitches and was done. We stayed for six more hours and he even got a few ABs and played the field as players left.)
Imo, no coach would dissuade a kid from playing scout ball. Yes, maybe the kid catches the eyes of the scouts and maybe he gets drafted and maybe he signs. So what? It's a credit to the college coach for identifying and signing such talent.
I have a cool picture of my son with a bunch (half dozen) of his scout buddies during a game - EVERY ONE of them got drafted (HS and/orcollege).
What a great time: the best baseball players in a region playing sandlot baseball and having fun under no pressure.
