It's fine so long as everyone's on board with PC death, but this is just an example of D&D struggling to hold onto a giant audience with conflicting views. If they get rid of death, the people who actually play D&D the way it's meant to be played get pissed off. If they don't, the more narrative-focused players (who really shouldn't be playing D&D in the first place) will get pissed off. So they just ignore it.
