In England it's the norm, nobody bitches or moans, the only rules regarding playing first team players in reserve is that only 3 can be named in the squad, they must have played a percentage of reserve team games to be eligible to play in certain cup ties and games after march to prevent influencing promotion/relegation. there is an enforced player registration with photo id which each official and club receives to stop players playing under assumed names. There is as expected no limit to reserve players being in first team squad.
It works well in Buckinghamshire, and perhaps if some of these suggestions were voted on at league meetings there would be less moaning and more transparency.
Its certainly not cheap to run one team never mind two
