Alright, next up is dynamic-plugin-yeet. This is an neat but old and completely unloved feature to support Rust hot reloading. It's wildly unsafe, not particularly well-documented, hasn't been improved in years and seems to have active UB.
As other experiments (like dextrous_developer) have been created, I've increasingly been of an opinion that this is an attractive nuisance. Others agree! Cart's the last holdout, so I'll bring it up next time we chat :)
