For blocking checks - I personally use notion of errors and warnings, with errors definitely going to quarantine and propagated to good data, and warnings going to both good data and quarantine. It’s a trade off between not blocking all data and having a visibility of what is potentially bad. Another approach is to send everything into quarantine, but then giving users an instrument for rescuing their data, and further tuning checks to avoid this happening.
