I think it's a perfectly OK idea, as long as you control the servers you are trying to access via this feature. The problem is about not sanitizing user inputs.

I think it's a perfectly OK idea, as long as you control the servers you are trying to access via this feature. The problem is about not sanitizing user inputs. You can achieve the same by forking a process whose file path is controlled by user input. Does it mean allowing a program to fork processes is also insane?
