> There are some valid points to keeping comments for posts that have since been deleted, and I don't necessarily disagree with them

Then your argument isn't about parent-child relationship, but value of the actual content. I can assure you, even if you don't give it value, there's one.

The funny thing, this is most probably why it's important to delete it if someone want to delete his content. It's his value, not yours, not Facebook's, no one else.

> It would be much better (with no loss in privacy) to at minimum just replace those comments with null text and a null owner, to at least show that 3 rows used to be here, between these existing rows.

I don't care about this.
