In Fedora/RISCV we have different machines and we schedule builds based on their requirements (strong single-thread performance, many-cores, memory to core ratio, and in general high-memory systems). We do a lot of individual assignments to the builders.

It would be a convenient if we could directly assign a task to a channel instead of a builder/host.

All builders are in 'default' channel, but we want to have more precision to target specific subset of those builders based on their specifications as described above. In some rare cases we also schedule builds based on geographical location (e.g. to avoid high-priority long-running tasks landing on builders where we have active weather event).

Today we can create channels and assign builders to them, but the logic to pick a builder would still be outside Koji.
