I have a general question here on the registration requirements with nested passes.

Is there a good rule of thumb for dependent dialects, external models and dynamically injected ops mixed with nested passes?
It seems that a mechanism to declare dependent passes would be a good QoL improvement: it does not seem manageable for nested pass writers to have to manually add registration for everything in dependent passes.

Am I missing something?

Dependent dialects is supposed to be handle recursively, which admittedly can be tricky sometimes. I think the IREE HAL handles it properly as an example:

External models are supposed to be injected by IR producers, if this is part of a nested pass, the pass that nest this can handle this in getDependentDialects() as well.
