This is exactly the reason why I'm saying:
ad1) You can't validate properly deployer dependencies/requirements in insert phase (domino algorithm tries to do it - wrongly)
ad2) You can do it properly only in method DeployersImpl.getDeployersList(String stageName) (i.e. sort lazily on retrieval and detect errors here and not in insert phase)

It's because you don't know the order in which deployers will be added to deployers chain. IOW you can't validate/sort untill you have full chain.
