Garbage collection algorithms are also applicable outside of in process memory management. I wrote a copying collector against a KV store in Clojure that I ran in prod for a while, though I swapped it out for a generational mark and sweep in Java. I'm sure somewhere, somehow, somebody has written a GC in Excel serving some kind of business need.
