It seemed the 'enormous' effort that needed saving was that of choosing a color for a shadow, because it's so much more desirable to let each browser pick a different one.  

I don't get how black is better than currentColor given that it is the default color for text in most browsers; why pick a default that's will be wrong the most often ? 

If this is so critical that hair must be split then let's require a color value. Any arbitrary value will be as interoperable and arbitrary as what we have today.

I'll just note that the model that's currently implemented does, according to you, already require authors to do just that.

Making it non-optional is my second choice. But that would require the enormous effort of implementors changing the value of some variable in their code. If they can do that, why not instead change the value of the constant they currently use, from "defaultColor" to something useful, like rgba(0,0,0,0.5)? Or even black. That way, if there are a few authors who wrote for a default color shadow to appear on their default text color box, they will still get a nice shadow.
