Currently this use flag does nothing. I would liked to get rid of the jupyter->nodejs+qt dependency.
Indeed, when I added the flag, in the commit linked below, I by mistake unconditionally depended on jupyter et al: https://gitweb.gentoo.org/repo/gentoo.git/commit/sci-physics/root?id=4cf3d9955693efdf7c3f4f4fcff869886fbae6d8 I don't know what is better, but probably just removing the USE flag is not a bad idea (and always depending on jupyter when PyROOT is enabled). Otherwise, the dependencies need to be updated to only trigger when the USE flag is enabled, because these dependencies are not really necessary to just use ROOT, even when PyROOT is enabled. However, I don't understand the jupyter -> nodejs+qt issue you mention.
> I don't understand the jupyter -> nodejs+qt issue you mention. Jupyter pulls in dev-python/notebook which in term depends on nodejs. Jupyter also needs qtconsole, even if I want root w/o qt5 (USE="-qt5"). If I just want c++-root (+python) I don't want to depend on nodejs and qt5 (i.e. some container image with root,etc.).
Ah, then what I should do is fix the dependencies, the intention was to only bring in jupyter and notebook with USE=jupyter. I will fix it now while I'm bumping ROOT to 6.30.00.

Thanks. In my case that reduced its dependencies from ~250 packages to only 17.
