there is no point in having any upstream if it's just going to run right away
anyways, right? Just use a root task...
That's correct - it only applies for dynamic task mappings, where the
`input` value is another operator (that's the actual check that I added).
As Elad stated, there could be some cases where `always` might be useful.
However, there's plenty of work to do in the Trigger Rule area, I'll try to
lead it when I have the time.
