KaOS Linux calls itself a "lean KDE Distribution", and it is certainly that, at least in terms of what is actually offered for download. Go to the KaOS Download page and you will find exactly one file (a 1.6GB hybrid Live ISO image) with one desktop (KDE Plasma 5.4) and one architecture (64 bit). No huge 'all-in' 4+ GB installer or tiny 'netinst' core-only installer, no other desktops (not even community editions), and no 32-bit version. Lean and focused.
