Every time it gets re-written, I run into the issue here: http://samba.imasd.elmundo.es/samba/docs/man/Samba-HOWTO-Collection/CUPS-printing.html#cups-raw regarding 'application/octet-stream' getting commented.

No, the types and rules are cumulative.  For example, if you have
another .types file with a definition for application/postscript,
the rules it defines are added to the ones in the mime.types file.
Similarly, you can just list the same MIME type multiple times in
a single file rather than using the backslash continuation stuff,
for example:

      application/foo foo
      application/foo string(0,foo)

is the same as:

      application/foo foo string(0,foo)

and:

      application/foo foo \
                      string(0,foo)

If you comment lines out in one file, they are just ignored - the
MIME type code treats comment lines as if they did not exist.
