The precedent set is interesting. If Dirk and DWade get a honorary All-Star do all future greats get one? And will there be controversy when one is not given one? It's a bit of a Pandora's box. Not Manu so much, but where was TD's final bow All-Star appearance. If the argument is TD didn't announce his retirement in advance, well, neither has Dirk.
In the big picture I don't care. All-NBA is more important than All-Star but for some reason the later is mentioned more often in career retrospectives.
