I'd guess that's for shops that are severally space and power constrained relative to their needs and/or need to move around immense amounts of compute. eg: sports media that need to ship container-offices around the world three times a year. Two of those, one as a cold spare, running immutable OS images, a honking big disk array, and thin clients or laptops. simplifies HVAC, power, noise control, and networking requirements, plus it's only one system to test, validate, and secure, vs a bunch of workstations.
