How to use `ModelicaSystem.convertFmu2Mo()`

[ondras12345]

I haven't found any examples or tests for it.

Do I really have to create a dummy .mo model file, load it and compile it (see ModelicaSystem.__init__()) just to convert a *.fmu to a *.mo?
At first glance, I think this function would be easier to use if it was a @classmethod that constructed a ModelicaSystem from the FMU.

@ondras12345 here is a test case which does that https://github.com/OpenModelica/OMPython/blob/master/tests/test_FMIExport.py

Isn't that the other way around? I see convertMo2Fmu() in the test case, but I was asking about convertFmu2Mo().
