I asked about this specific question several months ago because I was considering doing exactly this. The consensus was that it could lead to violations, and apparently it can lead to even worse problems.
Another thing to mention here. If an automated removal order does get created, you CAN cancel it to delay that process, but doing so is technically a violation of FBA policy. If it gets to the point where the automated removal is created without a resolution, that means Amazon is serious about these units being defective and is unlikely to ever move it back to sellable. In this case I would not double down on possibly creating another problem by canceling the automated removal.
FWIW, for my defective problem, there’s still a unit marked as defective after all these months, no automated removal was ever created.
