Oh, sorry, I thought you know that youtube-dl is a python tool. (I not
it since I'm using it myself).
Basically you were right: tools do not need to be propagated (at least
as far as I understood).
But the reason this needs to be propagated is: it is not used as a tool
(via some system-call or such), but the python package is imported, see
<https://github.com/mps-youtube/pafy/blob/develop/pafy/backend_youtube_dl.py#L11>.
I have to admit that this is not obvious.
