Yes, it does stand for water displacing, but I figured that refers to the water that's in the rust of rusted parts.  For drying ignition parts I've seen silicone spray; using a flammable spray like WD-40 seems a bit iffy.  Also, one finds WD-40 sold (in bulk as well as cans) in machinery catalogs, far from car ignitions.

And I've seen plenty of warnings against WD-40 in forums discussing metalworking machinery and firearms, or gunsmithing reference books.
