--- End diff --
since workflows are modeled as operations and dont have a unique model
type, and operations dont have a field describing whether they're workflows or
not, it's problematic filtering this via model storage. working with
service.workflows is simpler so im keeping this behavior for now, even though
its inconsistent with the other `list` operations since the user can't specify
the column to sort by etc.
