There is in fact a much better reason to think of them as programs. There's
not much distinction between having a 'program' run by an 'interpreter' and
having 'data' interpreted by a 'program'. We certainly consider programs
in interpreted languages like perl or python to be programs, not just
'data'. But similarly, an ASCII file can be considered a 'program'
executed by the interpreter consisting of 'cat' plus your console. An HTML
file is a 'program' interpreted by a web browser. Et cetera.

Not the difference between 'not distributable by Debian' and 'not
distributable as part of the Debian system'. Something is 'distributable
by Debian' if it can be legally distributed in non-free. That doesn't make
it distributable as 'part of Debian', in 'main'.

I certainly hope that to go in 'main', manuals will have to provide source
(preferred form for modification); otherwise, it's quite annoying to modify

If it was managed and modified as a .wav, the way I would, the .wav would be
the required source, yes. (Some people work directly with .mp3s, despite
the quality loss, for whatever reason.)

What practicality problem?
In the *binary* packages, you distribute the preferred form for installation
and general use. In the *source* package, you distribute the preferred
form for modification. People who aren't interested in modification don't
even download the source package. People who are interested do.
There are none so blind as those who will not see.
