@yafet-a you are right, currently instrumentation seems to work. Previous instrumentation issues could have been the result of independent bugs. Tbh I didn't yet test this part too much. 
I'm not sure if this would be a good project to take on, as it really depends on what the tests in this patch will look like, etc. But if you are interested in similar ideas/topics, feel free to reach out in private.
