There's a lot of rose-tinted glasses in this thread and this is coming from someone who grew up using computers with these sorts of icons and designs. I appreciate the aesthetic, but I still think that many of them are too difficult to distinguish on their own, regardless of whether they're in full-colour skeuomorphic or a flat line icon. As another commenter pointed out, a lot of them are just variations of a computer / folder / paper with other icons stacked on them in different ways or sizes.

In any case, you would want a supporting label to really convey the meaning.

While I love to see these sorts of icons in personal sites and projects, the reality is that if I presented icons like these to a client for a SaaS app in 2023, I'd be sent back to the drawing board. No serious business wants their UI to look like it just stepped out of the 90's.
