Module files are usually a reasonable compromise between quality and
size for soundtracks. The disadvantage of tracker files compared to
MIDI is that they are larger since they contain the samples. The
advantage is that you know they will sound identical no matter where
they are played and whether or not the end user has MIDI hardware or not
(if not, then you are also saving them CPU time on the soft MIDI
synthesis, and perhaps sounding better if they have only a crappy
wavetable GM).
They are advantageous compared to raw PCM streams also due to the small
size (like dictionary compression almost if you consider the repeatedly
used samples to be the "words" of the dictionary). That advantage is
mitigated somewhat due to high quality PCM compression such as vorbis.
Certain styles of music such as techno and instrumental music lend
themselves exceedingly well to module formats, where music with voice
tracks and lots of embellishments and such would probably be better off
composed solely in digital audio.
Recent games such as Unreal and Age of Wonders (among others I'm sure)
still employ module formats for their soundtracks. (.IT, .XM)

No. Open module formats can be played in any program. MikMod (used by
SDL_mixer) supports a lot of them out of the box. You are correct
though that a tracker software (such as classic DOS trackers, or open
source SoundTracker) is usually required to compose most efficiently.
You can usually use a tracker or module player to easily export module
files to digital audio.
