With systemd-nspawn, systemd-sysext & portable services, it really does feel like there's a space to be explored for a new systemd-based orchestrator.

I believe Facebook/Meta's infra is heavily systemd-based with their in-house Twine cluster manager but I don't know how much of the internals are available.

How close to fleet[1] do you think this might turn out to be?

Systemd would be used for setting up the containers / cgroups yes. But, it's a very small, localised implementation detail really.

Twine (the external name, but more often called 'Tupperware' - probably the better name to use in searches) would be hard-to-impossible to make available to non-FB use, and probably mostly pointless. It is very heavily integrated in with lots of other Facebook infrastructure, from the CI system, to the automated fleet roll-out system of services, to the service discovery and routing system, etc., etc.
