This is just something that I always wish there was something in POV-Ray where
you could just do something like:

#displaydefault {media}

#man media

or something similar.

I usually [try to] embed some sort of debugging output flag into my code so that
when it's enabled, the code spits out any (ok, every) relevant value.

Perhaps something to think about for 4.0 so that the software itself can answer
questions instead of / in addition to a separate documentation page.

Think "measurement", not "label".

Better documentation on what settings are used by each media method 
would be helpful for sure, but today the defaults set are the same no 
matter the method defaulted or set. In other words, there are not 
different defaults set for methods 1 & 2 should the user specify one of 
those in the media.

Aside: Not universally true, but often keywords and their settings can 
be given in any order in a block {}. Further you can often later in a 
parse refer to a defined 'item' and override some part of it. Useful, 
but this freedom makes having different default sets or sanity checking 
a group of settings for consistency during the parsing phase more 
difficult. The only place where I know we've today got some pseudo post 
parse checking is with patterns and in that case the extra verification 
happens only with the pavement and tiling patterns.

Yes. I since removed clipka from my address book (sorry, Christoph!), 
and Bill's name is showing up correctly now.
