I don’t think Gnome-Software is that important. After all it is a Gnome/GTK only software. If it was cross and/or multiple DE friendly I would. And Antergos already come with Pamac.
Also I just give a try to Gnome-Software and it is very very very limited I couldn’t access to all the software on the Arch repos, it look like it only give Gnome/GTK softwares as a choice (no QT soft as much I can see) and only FOSS (so no Steam, Skype, etc.).
So I don’t think Gnome-Software is a good choice for Antergos.
Oh and before I forgot on your blog you’ve written this “I don’t even have to enter a password when I install an app. What is this #sorcery? Not sure about the #security implications.”
It is not norman and never occure with pamac, yaourt or pacman itself so it is not Antergos related but Gnome-Software and packagekit fault. Pamac and yaourt ask for password once and you can use them for a time and after a short time will ask it again if you need them again, and by default if you haven’t change anything in antergos you HAVE to run sudo pacman (execept while root).
Long Live Antergos
