If you find yourself using the term bloated you should in most cases find a new word because it communications only imprecision. It neither uses excessive RAM, nor requires excessive storage, nor runs slowly. Do you mean it has too many features?

In the context of the prior comment which was choosing between Gnome and KDE the fact that applications require you to have half of KDE is meaningless as you are if you pick KDE going to install all of KDE already.

In the context of installing KDE apps outside of KDE this is fairly overblown. Most people have hundreds of GB to TB of storage available and will install games which require 60GB. At this point in time worrying about KDE installing a few gigs of deps is like worrying about the difference in ram used by Emacs vs Vim.
