I'd agree so long as the young goalkeeper isn't expected to be "the guy" that saves the team and only plays on goal the entire time period, and so long as the coach is working with the defense to make them more effective. Given that this is a new goalkeeper whose parent has indicated that he's coming out a lot (when it is unlikely the club has taught him, let alone helped him master, the techniques for coming out such as how to collapse dive properly in order not to get hurt), my antenna would be up.
An older would be a different story.
My son's U10 team got "the guy" keeper after suffering with a daring, but small keeper who couldn't punt the ball 20 yards. It changed our whole style of play.
He eventually moved on to a bigger club, and I saw him at a mid-teens tournament playing keeper, sweeper, stopper, and coming up to take free kicks, all at the same time.
