It’s very nice to not have a dozen different versions of the same distro to parse through and figure out that are simply the same distro with a different DE. Moreover, very few of them offer this many options.
Cachy could be doing a better job explaining what the user is looking at here and who each of these is for. Pretty easy to sum up in 1-2 sentences…
Being able to doesnt mean its recommended. I played around with that in a vm and it looks like some DE use same parts of the config files. Which result into inconsistent themeing/UI. Like random wrong colors, icons and fonts.
