I understand, but at some point sheer volume risks diverting/wasting community resources. Wallpapers are innocuous (an image is an image), but themes and extensions need to be vetted, updated and maintained as Plasma updates/changes over time, or at least should be.
Who is reviewing/maintaining 2,500 themes and 2,000 extensions, and how often? Does KDE have design/quality standards for inclusion in the KDE Store, and how does the team vet/check to ensure that themes/extensions comply with whatever standards are in place? The KDE team must be enormous to handle the load.
I'm not putting down Plasma, but I'm honestly shocked at the volume and wondering how the KDE team handles all this.
