in https://qgis.org/debian/ repository, qgis-plugin-grass depends on grass721, so it doesn't install if grass74 is installed.

But installation instructions for GRASS say:

Users of non-LTS release (like Ubuntu 17.10): Add GRASS Stable PPA
sudo add-apt-repository ppa:grass/grass-stable

So, QGIS and GRASS instructions don't line up.

Well, they don't have to as they are independant. You can install QGIS on plain artful and you can install GRASS on plain artful. But there isn't a build of QGIS that supports the GRASS installed from the GRASS ppa - and we don't claim there is. You need to build QGIS from source to support the newer GRASS on artful.
