PS7: 
Sergii, maybe you could have a look? Especially at the code which decides whether to replace previous output or print new line. I think it's the last remaining thing to do here?

I was thinking this patch can go ahead first (provided it's all good and approved), and it does not necessarily need to wait for CB:84439 ?
While I am still working on CB:84439

Thank you!
