Original author here, thanks for the comment! I also think that backend would be an interesting subject to try and reduce, if only to not constantly wade through 100s of Dependabot pull requests... It's a very different scenario where you will want to optimize different things (code size usually does not matter as much, for example) and you have various deployment options (serverless, containerized, edge, ...) etc. so quite the Pandora's box, I think. Interesting nonetheless!
