@maurelian seems like if we want to exclude the different proxy types we would need to create an L2ProxyAdmin from scratch because we cant override the functions if we inherit from ProxyAdmin.
If we dont care about removing the different proxy types then we can inherit from ProxyAdmin and just add the upgradePredeploys spec
