That's metapackages for you, someone out there changed their mind on what "plasma-meta" should contain. If the installation was done by installing specific individual packages everything would've stayed the same.

>8G being used
As in 8GB in the "Used" column? Or 8GB difference in the usable size? Usable filesystem size is always smaller as the filesystem itself takes space.
I have an EXT4 on a 464G partition with usable size of 461G. (tweaked the inode count a bit)

Linux distributions are at least partially to blame as they tend to package the entirety of systemd into a singular systemd package.

Please learn what package management is and comprehend the fact that there are no "apps", there's just a system.
