if asked, and if written as above, I'd suggest introducing 'unofficial' as a new
built-in variable which only exists if the keyword was used.  it could contain
the id string, allowing something like:

#if (defined(global.unofficial))
  #if (!strcmp(unofficial,"povr"))
  ...
  #end
#else
  ...
#end

aside - 'povr' emits a warning when I use unofficial, the 'beta.2' simply
ignores it :-).

have only used the snapshot setting a couple of times, to try.  found that
'convert' works just fine, no need for the "i version" ('file' too recognises
them).

I am hoping that your (+ JG's) work on the X window handling, and the "-win
thing" perhaps, will appear in POV-Ray proper (and before the heat-death of the
universe, ideally :-)  is anyone working on 'beta.3'?).
