(from the The Big, Fat Update ™️ commit)

If there's such a thing as a fake player in any commonly used Fabric mods (or FAPI itself), we should probably wrap that using Architectury. If not, we could make our own and maybe have the Forge fake player class be compatible with it somehow?

(Technically) would be solved by #202, though I'm still debating whether there may be a better approach to this
