hmmm.. I would check, and defintely compact the backfill. There are
sideways forces on this stuff as well.

From what I've read later, I would compact the hoe operator as well. I
have a hoe, for my own use. I reckon _I_ could do better than that!

You're not really wrong, but it may not be a concern. If the operator
simply veered off course and then had to go back and re-dig a stretch
properly along the line, then he's still in naturally compacted virgin
soils. He's wider at that point than he needs or wants to be, but as long
as he didn't horribly screw up his depth of cut either on the errant pass or
on the correction pass, he's fine. If not - that's what tampers are for.
Bring it back up and compact it.
