Almost is the key word.

We have at least 3 implementations to do exactly that.  It's unlikely that all 3 implementations accidentally do that.  It's also unlikely that the code is writing itself.

That suggests that there is at least 1 person.

Drawing your conclusions from "everyone probably agrees with me, there's a minority that don't" is a statistics game that leads to all kinds of fun results.

Perhaps if you felt so strongly about this, then the original edit that added box-shadow or the re-edit that introduced it should have said something like...

"When color is not specified for <shadow>, the default must be a fixed color that is not completely transparent (alpha > 0).  Exactly which color is UA-defined but here's a list of colors that we think are bad choices ...."

But that's not where we are.

It sounds like we're going in circles, so I guess CSS3 should just leave it defined as is and CSS4+ should gain some teeth so that we clearly indicate that (a) transparent as default color is not conformant and (b) any other desirable aesthetic for the default color be expressed explicitly rather than left as UA-defined.

The current state is that we apparently have a "totally surprising to almost anyone" implementation across at least 3 browsers, even though at least one person is depending on that behavior already.
