If the netlist and PCB layout is correct then why waste time on
making the schematic look like you want it, only to be told by
someone else that they would have drawn it completely differently?

When I was a service engineer there was no such thing as a schematic and I
often had to make do without a circuit diagram at all. On rare occasions a
repair had to wait for a circuit diagram to arrive by post and when it did
it could easily contain circuit A.

I suppose it depends on whether it was drawn by a wireman or by the
designer.  Small firms often benefit from more direct contact between
the designer and the user or repairer.

 
Many circuit diagrams I encountered were clearly not drawn by the
designer. Another issue with circuit diagrams from times gone by would be
a line which went nowhere because it joined to a line on another page
which may or may not be easy to find.

I try to draw my circuits as one big drawing, but if I can't, I try to
make the lines from one section to another appear in the same order down
the page with clear lettering or numbering (and possibly a bracket
around them with a legend to say where they go).  I'm usually the person
who will have to make sense of them years later, so I feel I should
leave clear instructions to myself so I can see what I was doing.
