jQuery .nothas?

Question

Is there a way to do the equivalent of a .nothas() selector in jQuery? For example, if I wanted to add a TBODY to all TABLE elements that didn't already have one, it would be nice to do something like this:

$("TABLE").nothas("TBODY").append("<TBODY />");

It would be even better if this could be limited to direct descendents, so that (in this case) TABLE elements embedded in THEAD cells wouldn't be considered.

jQuery has :not and :has selectors:

$("table:not(:has(tbody))").append("<tbody />");
