-1 to it. During last Summit, we agreed on externalizing current
Scheduler code into a separate project called Gantt. For that, we agreed
on first doing necessary changes within the Scheduler before recreating
a new repository.

By providing select_destinations as a new API endpoint, it would create
a disruptive change where the Scheduler would have a new entrypoint.

As this change would need a spec anyway and as there is a Spec Freeze
now for Juno, I propose to delay this proposal until Gantt is created
and propose a REST API for Gantt instead (in Kilo or L)
