A similar function is often needed by themes for taxonomies (mostly categories), for example the latest default themes have contained a function `*_categorized_blog()`. I think this functionality is essential for several themes, and we can make their lifes easier by providing these functions to them (especially since several theme authors don't really wanna mess with hooks for invalidating transients). Of course, for backward compatibility a theme should check whether that function exists, and if not, it still needs to take care of things by itself. However, I think this will still be a good solution long-term to include this functionality in WordPress Core.",enhancement,new,normal,Future Release,Themes,,normal,,needs-unit-tests has-patch,,
