<upd_detl>Not rare, but the xref should probably be used in most everyday cases.

I get the feeling this is used especially in special explicitly-inclusive contexts.  This appears in some policy/legislative directives ("sibling abuse").  I saw as a translation for "all of my brothers and sisters who suffered under ..." in a dramatic speech(semi-figurative, members of the same race oppressed by another race. but it's sci fi, and it was a "collective" society, so who knows...).  daijs explicitly says same as senses [2] and [3].

There's another reading on wikipedia and wiktionary based right off the alt. reading of 兄弟　（けいめい）</upd_detl>
