Should conceding defeat be allowed?

This brought to mind a middle school game I was calling as PU last year. After one inning, the visiting team was up 14-0, the home team out on three successive strikeouts. After two out in the top of the second, the score was 19-0. The home coach asked for a conference with me and the visiting coach. The home coach told the visiting coach basically, it's 19-0, have all your players batted? If so, I'd like you to just let all my players bat and let's go home. They agreed; the players switched sides with the visitor's third string pitcher taking the mound. She was obviously trying not to blow the ball by the batters, but she still struck out the team (yep, team, all 9 batters).
