In the olden days, people in charge of institutional IT probably would have just gone ahead, give it a try, see what happens. In today’s “professionalized” IT setups, that likely requires a feasibility assessment, a user requirement study, a policy draft, a multi-year budget prognosis, and endless meetings (probably forgetting some) before the first stone can be laid. By which time Microsoft 365 offers Mastadon instances, which defeats the whole centralization idea. Apologies for the sarcasm.
