Create a Scheme package manager!
Be careful what you wish for.
In time to come, there will be a chapter in every Scheme textbook showing how to implement a "simple package manager" using Scheme.
Before you know it, there will be a million "minimal package managers" for Scheme, all incompatible with each other.
This is what Schemers have always done. Schemers cause fragmentation in whatever they touch.
Schemers spend all their time scheming about schisms.
Schemers prefer to dream of perfect minimalism that never arrives, instead of spending time to create a practical solution useful for many.
