As someone who took ownership of a large codebase from a genius former colleague who rarely explained himself, the only reason we kept the code was my insistence on replacing cryptic code 1-liners with easier to read/maintain multi-line expressions that had terse-but-readable variable names and //inline comments.

The team ended up expanding the codebase quite a bit before that technology stack was retired a couple years later. Not sure if it would have survived without that refactoring.
