Of course the Rust fanatics do not like it. But it is really not so much much about Rust - it is more about technology interop.
I am sure that X/Rust is faster X/TS and that Y/Rust is faster than Y/TS, but that is not their point - their point is that X/TS+Y/TS is faster than X/TS+Y/Rust, because the switch between TS and Rust comes with huge overhead.
