@akurtakov As far as I can see, the warnings are not being introduced by my PR. I don't think there is anything I can do at the moment.
Please let me know if I am wrong or if I can help.

[akurtakov]

Warnings are due to new stream opening and should be fixed with #2826 . I'm rebasing this one.

[akurtakov]

Thanks for this one! Much appreciated.

@akurtakov Thank you for the effort you put into this PR :)
