I don’t think it is necessary, as @navordar mentioned, just pick a smaller server, maybe have two or three accounts on different servers for now might work, unless you are willing to host an instance that will help grow the federated network.
Hosting your instance, might require some commitment, good admin skills and transparency.
I am inspired how the arch Linux community handles their admin for projects, I believe whoever hosts a instance that follow the same philosophy, that instance might stay active for a very long time.
