Hey @Mirrrrrow,
while I appreciate your contribution, this branch is a work in progress. The entire codebase will be refactored. We didn't forget to use the lib cache in your proposed changes, we just haven't gotten to it yet. Due to the nature of this branch and what we have planned for it, we don't believe it's suitable for PRs at its current stage.

Any contributions to the dev branch are welcome though!
