Well, I hope I'm wrong. It's just that the first impression is more confusing.
If I wanted a minimal install to build from, I'd simply download the Net edition. It offered a minimal install and that's what it did. Now I have to download a DE ISO and deselect the DE to achieve the same thing? I assume this option won't be restricted to Lxqt, but the thought of downloading, say, a KDE ISO when my intention is to install nothing but a lightweight window manager is hardly straight forward.
As for Manjaro-Architect I have to admit I missed completely that it had been officially released! I only saw this post where one was greeted with the words "THIS IS NOT READY FOR PRODUCTION ! ONLY USE IN A TEST-ENVIRONMENT !" I'll certainly try it out now.
