There are some electronics products where schematics hardly convey anything. Heavily digital stuff is often just a whole bunch of squares with dense rows of lines connecting them. Maybe a few caps and resistors here and there.

For analog stuff though, a schematic is absolutely fundamental to understanding how the circuit works and how to troubleshoot/fix it. Handing an engineer a code description of an analog circuit will basically have them just trying to mentally build the schematic in their head while reading it.

Imagine a model sharing 3D printing website that got rid of all the 3D model representations and just put the model code in their place. It would be borderline useless (despite your 3D printer having no issue still printing the stuff). Similar situation.
