First, POV is highly automated.  That is, it is perfectly possible to 
start a render, walk away, and get the finished result.  Interrupting 
this process to ask a question would be a change in style (not 
necessarily bad, just needs to be pointed out).

As far as "specifically [writing] in the camera block" goes, scene 
authors already do that.  They use the "up" and "right" vectors, as well 
as the "angle" keyword, to define very specific viewports into their scenes.

Omitting these parameters is not the same as saying you don't care; it 
is still saying that you want a very specific set of parameters, just 
that these parameters happen to be the default ones.
