That sounds valid. But by that same reasoning, shouldn't a well-known ward in Saigon also be tagged as place=city? If we do that, you'll have a big text label for the ward right next to the main 'Ho Chi Minh City' label, which doesn't look good. If we tag it as place=district, the label disappears entirely. And if we stick with place=suburb for now, the address lookup issue remains. So, if we're going to keep using place=suburb, we'd have to remove the old city nodes to fix the address problem, but this seems undoable since we keep these for navigation. That's what I think, at least, if we find another way to fix the address lookup issue, that would be great. After all, the main purpose of this changeset is to correct only the address, and not for aesthetic reasons. I'll leave this changeset for now.
