Software/code rots if not touched for months. This is such a fruitless effort but does get Github some good PR. They should instead preserve ideas that make all software happen.
I find the assumption that software rots after months a sad thing. Most of that is poorly versioned libraries that change quickly. Something like the Go 1 compatibility promise means code written just against core Go should be fine if someone has the latest (maybe last) version of Go 1.
Also archeologists study rot.
