@FediverseSymbol Asterism does not exist in a vacuum. It was not added to Unicode for fun so that it's use case could be found later.
Asterisms are still used for purposes such as dinkus. Indeed I regularly use it for that myself.
Attempting to repurpose an already used symbol has strong "move over loser, we are taking this" vibes.
You want something that is part unicode? Fine, do it the hard (but correct) way like everyone else and submit a proposal.
