IMO the author could very much submit this to a demoparty in the "demo" category (assuming they'd substitute the music with a fitting original work).

These days, the only notable difference between demos and intros is file size. If it's bigger than 64kb, it's a demo. You can totally have a short, single-effect demo like this one, and there's plenty such demos out there.

Ergo, I disagree, I think this counts as "full-blown" for any reasonable current definition.

Fair enough. The definition of a demo in the '90s was definitely multi-part: multiple effects with usually still graphics in between (such as group logos or pixel art rip-offs from fantasy paintings). A single-effect demo that wasn't an intro would have been rare.
