Well, it is somehow part of,

    * Transactional upgrades and roll-backs
    * Reproducible build environments

I would also add Inferiors and Time-machine, especially working in
tandem with Software Heritage.  AFAIU, it is unique to be able to jump
to (almost) any point back in time and just rebuild (or almost), with
one command-line, whatever the state of the world (or almost).  It
pushes far beyond features such as https://snapshot.debian.org/ IMHO.

Cheers,
