That seems like the only practical way to implement such a server, indeed.
Not only practical, but also the right one, IMHO
The use of jsonrpc.el, an existing Emacs library for JSONRPC communication, as well as parts of the Eglot LSP client (also slated to be in Emacs core) can more than likely help when doing this.
Even though Eglot is a LSP client, a very significant part of its code could be used in the server.
If there is serious interest in making a eglot-servel.el, I can arrange the split of eglot.el into eglot-common.el and eglot-client.el libraries.
