Oh, I know what you mean.
But that was exactly the reason for having a .DLLs folder, isn't it?
When you place an assembly into this folder, you avoid having to write
this boilerplate code, and simply import the assembly as you would
with a normal python module. At least, that´s how it worked in
previous versions...
