You are kind of ranting here and your point seem to mostly be "but we should not do harness engineering at all" which I agree with btw.

I am describing the reality we are currently in. If I don't do some harness engineering then my bots crap on the floor and I start questioning whether I should delegate to them at all and if me doing it manually wouldn't still take less time.

And you are describing a desired reality. I sympathize, mind you, it's just not the one we are currently living in.
