I think WASM will likely take over as the standard for shipping things like Functions-as-a-Service implementations, and other forms of plugins, where one host application/server of some kind wants to efficiently run pieces of untrusted logic. I really hope WASM takes over as a plugin mechanism. I don't think it will lead to fragmentation because communities will form around their preferred language, it will just not be enforced anymore. And forcing a plugin language did not work so successfully to prevent fragmentation anyway, see GNU Guile or vimscript.
