Since xenharmlib is written in python it is not suitable for real-time audio because of the latency that an interpreted language introduces. I think if someone was willing they could port the library to C or Rust rather easily, because apart from Exceptions the coding style is functional and stateless. AFAIK Rust has some libraries that provide a VST interface.
