We can create up to 50 Group roles but only 5 of those can be management roles, and one of those is a Group Owner role, so in reality we can only have 4 Management roles.
This is not even nearly enough, considering the fact that the role becomes a "Management" role as soon as it has for example View All members during normal use you run out very quickly.
I believe the amount of Management roles should be increased to at least 10. This allows us to have 9 different management roles, so we can properly choose which permissions we want to give which role.
