Although I have been in electronics only 30 years, I must say that your view
is typical of most engineers I have worked with. This doesn't mean it's
RIGHT, just typical.
It is NOT the young engineer's design, it is NOT the layout designer's
design, it is the COMPANY's design. It is a waste of the COMPANY'S money
having each engineer being able to change pinouts on a WHIM when the
supplier documentation specifies pin numbering. It is a waste of the
assemblers time having to count pins if they need to trouble shoot the board
because the pin numbering on the schematic does not match the pin numbering
molded into the part. It is a waste of the customer's time (and a "black
mark" on the company's reputation) trying to figure out what the heck was
going on if they try to repair the equipment. And using the excuse that "it
isn't MY design" doesn't help, and hasn't helped in a LOT of years. If
there is no pinout specified, then only ONE pinout should be defined and ONE
library part used, the designer's time IS NOT the engineers time, it's the
COMPANY's time, and redundant effort is a total and unnecessary waste of
money.
Like it or not, it's a TEAM effort. Catering to WHIMS is for children, it's
time to grow up, get the ego out of the way, and help the bottom line.

Ron:
This is an interesting, and IMO, distorted view!
As the layout designer, it is 'our job' to follow the instructions
given by the young engineer in all things in HIS design! He is the
'Creator', you are the artist. Give advice if you must. However,
advice is only "advice" and it is up to him whether to follow it or
NOT!
Connector 'Pin' numbering is often arbitrary, and I have seen many
mistakes with foot prints which I thought were according to some
standard, and they were not. But when I am only rendering someone
else's design, they are always the final authority.
Just my perspective as someone who has been an Engineer and a
Designer for over forty years.

Karl,
As the layout designer, it is our job to train the young engineer in
good practices. Having multiple symbols with different pinouts is a
librarian's nightmare and will surely screw up the assembly process
with
unnecessary delays. As a company(read team), we have customers. Who
takes the heat when the layout is wrong? I can tell you it isn't the
engineer who insisted on a wrong concept. Being a designer is so much
more than being someone who hooks up wires.
