I believe that was a suggestion for avoiding over-zealous stripping with etree's `strip_tags()`. `strip_tags()` finds tags to strip by type name, not by element pointer, so it's possible that it'll strip two sibling nodes with the same type name when stripping only one was the intent.  Therefore we suggested changing the type name of the intended `strip_tags()` target node to something that won't likely be found in the wild (ie. 'delete') to avoid this situation.

On the other hand, `remove()` takes an already-defined node as an argument so there should never be an ambiguity in what it's removing.  Therefore the tag name change to 'delete' is unnecessary.
