trwnh so in practice it ends up being one protocol per software release -- "mastodon 4.4" is not the same as "mastodon 4.5" nor the same as "akkoma 3.10.2" nor the same as "misskey 2025.12.1". they just happen to incidentally overlap in some places. and other softwares like lemmy will overlap less, and softwares like funkwhale may not overlap at all in any practical way.
