Is your feature request related to a problem? Please describe.
When removing a block from a pipeline, most of the times that blocks remains unused and stay in the filesystem until someone does some housekeeping and removes them directly.

I would love an option to delete said block when removing it from the pipeline.

Describe alternatives you've considered
The only alternative is to have a proactive housekeeping strategy and keep and eye on unused blocks.
