trace.h dead?

https://emscripten.org/docs/api_reference/trace.h.html

Here are 3 ways of using this library:
1. Google extension https://github.com/google/tracing-framework which is dead 3 years ago and doesn't work
https://github.com/google/tracing-framework/issues/589
2. Noname library https://github.com/waywardmonkeys/emscripten-trace-collector for python2 which is dead 6 years ago
Here is a fork https://github.com/feserr/emscripten-trace-collector and it works with python3 but this whole server has ugly GUI and also it doesn't gives an ability to save the report to open it in google framework GUI
3. Manually embed google framework http://google.github.io/tracing-framework/getting-started.html which is a huge unflexible crutch.

The third way has just worked for me but it requires manually adding these scripts into debug builds which isnt really easy to use
