Confused about zero component orientation
I agree with you: standards and practice are not inline with each other.
I have done quite some investigation on this myself.

In summary:


The component orientation in the design file should be the same as the orientation on the tape.
Even if the orientation in the design file is wrong, I did not meet a single manufacturer that complains about this.  They always ask the customer to validate the orientations.


Yesterday, I verified an online tool of a PCBA manufacturer that allows you to check and correct the component orientations online.  There were quite a few orientations that were incorrect while the footprints definitions have the correct designed orientation according to IPC-7351.

Despite that, I do check the orientations of components.  Generally the orientation on tape is mentionned in the datasheet, sometimes you need to go and find it in the manufacturer's "central" documentation where they list all specifications of their packages and orientation on tape.

You do not need to know the position of your PCB relative to the tape.  The orientation is defined by your design files.  The manufacturer copes with the difference of orientation between your design file and the actual panel orientation.

Even if various sources disagree with regards to the orientation of the quadrants, what is important is that quadrant 1 is the upper left.

The manufacturing houses that I consulted with regards to the design rules said that they can pretty much do anything - but they do not tell you at which cost!

If you can, you should define your footprints according to the actual orientation on tape.
In practice you do not really have to care too much, the manufacturing houses are used to the fact that there are many discrepancies.
The built-in footprints in KiCAD generally need some rework anyway if you want to have a better fabrication layer for instance.  I prefer putting in some time up-front, which avoids most of the placement errors to finally correct only a few.
