Normalize registry class instantiation

[ab93]

Summary

Currently, the different registry classes are not fully homogenous in terms of config-driven instantiation. A better way will be to normalize the init arguments.

Use Cases

This would be really beneficial in config-driven initialization, in a way that changing a registry will all be about changing the config and no-code change.
