The perspective of the author, in this instance, is best served by the 
functionality that's been explained.  If the opacity of the element were 
not independent of the "tangibility" (i.e. pointer-events), there would 
be no way to achieve certain effects, while the reverse is not true.  If 
we specified it the way you've requested, then authors would be more 
limited in what they can achieve.

As you know, SVG is a rich language, in which there are various 
different ways of achieving the same or similar effects.  I suggest that 
for the case you're describing, you could get at it another way, perhaps 
without the need for a mask.
