Pete brought up bonding in another thread. 250-148(a) requires the EGC to be connected to the box, however, in Nebraska the AHJ does not have a unanimous opinion that this is a good thing, so most inspectors are not enforcing it. We always run a EGC, even where we would be allowed to use the raceway as the ground.
The company opinion is that bonding at the box creates parallel paths for the ground and that's a bad thing. Bottom line is we don't do it because it takes more time and the AHJ doesn't enforce it.
What do you think?

I don't see how you can avoid violating the section I have quoted below if you do not bond the EGC to a metallic box.

Continuity and Attachment of Equipment Grounding Conductors to Boxes.
Where more than one equipment grounding conductor enters a box, all such conductors shall be spliced or joined within the box or to the box with devices suitable for the use. Connections depending solely on solder shall not be used. Splices shall be made in accordance with Section 110-14(b) except that insulation shall not be required. The arrangement of grounding connections shall be such that the disconnection or the removal of a receptacle, fixture, or other device fed from the box will not interfere with or interrupt the grounding continuity.
Exception: The equipment grounding conductor permitted in Section 250-74, Exception No. 4 shall not be required to be connected to the other equipment grounding conductors or to the box.
(a) Metal Boxes. A connection shall be made between the one or more equipment grounding conductors and a metal box by means of a grounding screw that shall be used for no other purpose, or a listed grounding device.
