I dont think so , I have watched several lectures on the
free body diagrams and I never considered this type of diagram valuable as all forces are not included.

in the diagram I posted with the block and incline the incline
is showing as a force , but not the force that the block would
exert in the opposite direction.

I think its best to include all forces in our
discussion as you might try to slip something around
a corner to lean the discussion in your favor.
