Actually we decided to use `_require_attrs security`, rather than a new
_require_capabilities() helper. We need a chance/requirement to add
that helper (when a test case really need it).

So I hope know is `_require_attrs security` enough for you? Or you really
need a specific _require_capabilities helper?
