Detailed
In my area, sometimes we just say it that way.
As a Chinese, I don't quite feel like to go that deep into the source behind, nor did I really care about there're some three other characters hacked off.
But now, if you wanna me to say something about it, yes I can.
Four-character phrases, idiom or not, are pretty popular my area, pretty popular all over China too.
In China, people talk faster than foreigners thought, so seven character version is not so effective, it's like a poem. Four character one is welcome, and because we have hundreds of, or maybe thousands of, never count it, informal/formal four-character catch phrases.
For those who utter out this phrase, probably they don't care about literature, that's what used to be the paraphernalia of notable men.
鍋碗瓢盆 are the everyday kitchen utensils, so they match the flavors, seamless.
