I didn't absorb all of what Alan wrote on my first and second quick readings, but here is what happens in the Ada initialization. The Ada binding, when initializing package plplot.adb or plplot_traditional.adb, makes several calls to plgcol0 as part of the color map 0 snapshot function--an initial snapshot is taken so that the user can later restore the initial colors if desired. No other calls are made. These calls to plgcol0 take place before plinit (which is normally called from the user program, after Ada package initialization). I did not put plinit into the Ada package initialization because I understood that there are other, optional, "pre-initialization" set-up calls that the user can make, and these must come before plinit. Except for those, the Ada package initialization could have been made to call plinit, relieving the user of doing that.
