Lapce dev here. Thanks for posting this.

One thing I would like to highlight about the WASI based plugin system is that, on this release we’ve finalised our API design. We call it "Plugin Server Protocol", which includes everything that LSP has and extends it with more stuff that a code editor needs. We hope that "Plugin Server Protocol" can evolve into something great that future code editors can use. It will be win-win-win for editor authors, plugin writers, and users. New editors don't need to start from zero for plugins. Plugin writers write once to support all editors that are compatible with this API. Users have more plugins to choose from.
