Based on an off-list discussion, there is a desire for "bus" connection functionality to handle many components/processor groups routing similar output to a common error-handling group or similar shared functionality.
While it would require substantial modifications to connection behavior to enable this, an interim solution was discussed where funnels could be chained to provide a similar mechanism. However, these chains can appear visually noisy (see screenshot).
I propose that we enable a boolean toggle for each connection which can mark it as "quiet" – i.e. just a line, no status display. This flag could be automatically enabled for connections between two funnels, as there is no possibility of starting/stopping the endpoints and no need for back pressure (display; it would still propagate from downstream connections) between two funnels.
This allows for very consistent connection/queue implementation and minor logic change, while muting the visual noise.
