Yes it will be close to perfect, even though schematic is only used as is and generated netlist is currently not used it feels like a good idea netlist is correct. Will try to figure out how it should look then professionally done.

In the cabinet I am looking at right now cables have a printed number and there is a printed number on terminal block so the number is essentially a net name. I have also seen Chinese sell numbers to put on there terminal blocks but in this case I think they number each row individually and in such case there is a problem which row. I found the number on the terminal blocks make it easy to find nets.

The circuit boards I made schematics for are used in automation and I need the schematic for documentation purposes.
