Sure. That's why that section starts off with 'In some cases...'.

I just wanted to warn people, without trying to define a list of good or
bad usages. If the text makes them stop and think, that's as much as I
want to do, especially if they've got a problem and need clues to direct
their debugging efforts.

I'll wait a couple of days to see if there's more feedback before
committing the patch.
