Hello,
The Clipping Sections and Clipping Drawings combinations are amazing for creating dynamic drawings for fabrication. So when we have to review the model, we don’t need to manually make2d again or keep micromanaging object view options on details.
However, using the detail and projection of the model space can sometimes make things hard to manage given the amount of objects that might be present on the model, as well as other studies.
The Auto-Isolate proposed in https://mcneel.myjetbrains.com/youtrack/issue/RH-90007 is already a step on the right direction to help solve this problem, so I would like to propose one aditional feature.
The option to create the first and third projections with ClippingSections, I currently do this creating a bounding box of the objects I want to add, and them I create a section on each plane and one looking from one of the top corners of the bounding box to the oposing corner, with help of Orient.
If we could somehow automate this process and give it the option to Isolate to Viewport, it would be amazing for creating drawings that can be easily updated if needed.
This removes the burden of having to micromanage objects view status and layers view status on each of the details of the drawing making it easier to manage the objects of each viewport by the Clipping Planes Panel, that is way more intuitive and easier to manage.
Another related request would be for the Detail command to have and option FromClippingSection
that would be another way of achieving something similar in case you created all the Sections before starting the Layout drawing.
Below an example of how I use the detail views to create the drawings for assembly, note I removed all names and drawing blocks and tables to avoid troubles for me.
But basically, I have a bunch of details, where I isolate the objects/layers to create the exploded view and/or step by step assembly for the workshop workers with the technical view option.
I think that using the ClippingSections to manage this would make it way easier, but it would need the option to add detail from ClippingSection 
And yes, the safety rails were fixed on the final version of this wheeled stairs, it was unaligned with the steps for a reason that later was discarted by the final client.
