Yeah, with permanent delisting of the entire company as the penalty. Of course, these people don’t care. They’ll just spin up a new seller and thus the only people you end up hurting are legitimate partners updating their product line.
Updating product line or need to amend something? No problem. Allow to add new content. Insert a link to the new version or a notice at any time.
Just never allow to edit existing content beyond a few typos. Updating product line and want to keep reviews? Sorry it's dishonest even if seller thinks of itself as "legitimate".
I don't think in the end any legitimate seller is hurt.
