Webpack 5 Caching

[busybox11]

Caching does not seem to work with Webpack 5 using this module as a loader. By looking at the code, on the file loader.js, it looks like it is only initializing the cache for Webpack 4 (I'm not sure though). Is that the intended behavior? If not, will the cache permit me to keep generated assets for future compilations, in case said assets haven't changed between production builds? Thanks in advance!
