Player Restrictions/Ejections, Playing Shorthanded

Question: A team can start/play shorthanded (one less than required/starting). If a team doesn't have a substitute to replace a player that has been ejected, the game is forfeited since the shorthanded rule does not apply here.
The question is on restrictions to bench -
I believe a restriction is equal to an ejection. If a team doesn't have a substitute to the restricted player the game is forfeited. The Umpire enforced a rule/penalty and therefore if the team can not replace the restricted player, the game is over. They cannot use the shorthanded rule and take an out.
Am I correct on this ruling?

Answer: The rule is written as just ejection. The philosophy is that ejection is the penalty for the worst actions (fighting, ..) and that restriction to the bench is slightly lesser.
We could debate whether it should be that way and which actions should fall in which category but that is the intent.
So if a player is restricted to the bench, the team can continue shorthanded.
