I'd say that removing barriers can be considered a part of canonicalization, which helps the compiler reason about the code (we have passes that acts based on number of barriers and etc.). However, I agree that we should not be calling an expensive pass too frequently in the pipeline.
I found this discussion valuable. Thanks for taking the time to discuss it.
