Could you add a little context to the PR description?  i.e. Why is this better?

Does this change also remove the old `config` global or just stop using it?   

Objectively this still like a regression in readability since it adds more visual noise and indirection.    However, I get that we are trying to make lld more library-friendly.   I'm just a little sad that it comes are this readability cost :(
