Oh for sure. But for now, this is a more than adequate solution, given how it is quick and easy to do. (Before I had realised this, I was also working on a userscript which used ffmpeg.wasm to literally load every single offending upload and extract a frame to be used as a thumbnail. It should be obvious that this would've caused considerable trouble as every single access/page reload would both use lots of resources client side, but also bandwidth server site)
