Most of the network seems to disagree with you. Reactions are a great source of social signal. Yes, clients should be smarter about not over-simplifying the meaning behind emojis. But you're missing my point, which is that coupling reactions with reports is also bad. I know you keep saying that's not what you're doing but... it is. The same button does both things, and you only tell the user about the report, not about the reaction,
"Most of the network" is not even coding reactions correctly, so apologies if I don't give them any credit...
