"... instructor earnestly describing to a student the importance of ripping wide boards into narrower boards and then regluing to make "stable" panels."

In my experience that sort of advice is quite common, Bill. It often makes sense if they're talking about boards that are showing signs of significant instability or warping where what they achieve isn't actually more stable or flatter; they end up, through the cutting and rejoining, making a glued up panel where the end result is a panel where that warping or instability is parcelled out into narrower sections within the width that can be coped with, e.g., a series of cross-grain ripples rather than one significant cup spanning edge to edge.

But, to reiterate and bolster what you say (again, me saying it) if the board is pretty much flat to start with, there's no particular reason to think that it will suddenly start warping when put into service, all things being equal. Slainte.
