package oneconf install oneconf-query but documentation is missing

$ dpkg -L oneconf
...
/usr/bin/oneconf-query

$ man oneconf-query
No manual entry for oneconf-query
See 'man 7 undocumented' for help when manual pages are not available.

$ man 7 undocumented
No manual entry for undocumented in section 7

If command oneconf-query is installed in default PATH, I would expect it to be documented. Otherwise I would expect it to be located only in /usr/share/oneconf/oneconf-query to be used by other programs but never by humans.
