Such editions are only for very limited and specialized target group. I have a one very weak, old laptop that my dad is using. I can't put there any openbox or similar kind of edition. Those are too weird and programmer specific. LXQT or LXDE are the lightest reasonable ones. They are still slow, but that's the farthest I can go.
From what I experienced so far, usually people with a very technical mind and with IT background enjoy those minimalistic editions. Those doesn't matter that much, because such persons have skills and knowledge to cook something on your own (on arch), but still, enjoy some editions for them. Also, they rarely need such lightweight systems, they just masochistically like having all very basic and light.
There are linux distros that do opposite: they prepare the extra large iso and pack everything they can to the system for potential offline usage by different people with different needs, usually having no knowledge about computers so everything must be user-friendly. And those distros are for not only developing countries but third world countries who have almost no widely available internet infrastructure.
Anyway, I like LXQT but it's still not matured yet and has some kinks to work out. Translations are not full (opposite to plasma, gnome or xfce) so there is still too many only English components. Sound applet is broken after install and you need to add one manually. Searching is not cleared after closing menu. No shutdown like applet. Other then that it's quite fine.
EDIT: This time installer worked and everything went fine.
