Not as an immediate safety feature, but to facilitate installing a flush ceiling without having to redo the wiring or expose it to screws and nails?On a second note, I never understood why the NM cable can not be stapled to the underside of the joist. I don't see the difference between it and going through bored holes of the joist.

It is arguably more exposed to damage from objects, etc. than it would be when recessed above the bottom of the joists.
Is it code compliment to install NM in a drop ceiling in residential and staple it to the underside of the floor joists

It is to protect smaller cables from the physical damage of hanging objects from the cables in basements, and from being snagged on passersby in crawlspaces.
they should allow an exception if a drop ceiling is installed in a basement
334.15 Exposed Work. In exposed work, except as provided in 300.11(A), cable shall be installed as specified in 334.15(A) through (C).Related (?) question: would it be code compliant to run NM along the top of a valance ?
So when you guys run some NM cable across a drop ceiling, you drill holes through every joist? Sure you do. :happyno::lol:

I don't because it's not required. A staple every 3 or 4 joists and that's it.![]()
It is not required unless you install a running board.
