Review comment:
Hey @wangyum, could you please add some detail comments here to explain why
we want to exclude these dependencies? I can tell why we want to exclude them
but it would be hard for other maintainers to figure out the intention in the
future.
(In general, I'd say every single non-trivial dependency treatment, like
exclusion and shading, should require a detail comment to explain the
intention. Unfortunately, we are not doing this historically.)
