The only case in which I see the point in using the constellation symbol for Fedi is on Gemini, where using images as icons isn't an option, while Unicode symbols, including emojis are already widely used. It can be used to denote a link to Fedi profile and I think it's going to be adopted without any centralized initiative — most good ideas on Gemini get picked and and widely adopted as community is rather tightly-knit and small in numbers 🤷
