'decodeByName' require same number of rows?

With too many columns, decodeByName silently throws away the extra columns:
> decodeByName "a,b,c\n1,2,3,4" :: Either String (Header, V.Vector (HM.HashMap String String))
Right (["a","b","c"],[fromList [("a","1"),("b","2"),("c","3")]])
It also happily parses a row with too few:
> decodeByName "a,b,c\n1,2" :: Either String (Header, V.Vector (HM.HashMap String String))
Right (["a","b","c"],[fromList [("a","1"),("b","2")]])
Is there (or should there be) a parsing mode which requires the same number of columns per row as there are header rows? There seems to be support from the spec:
Each line should contain the same number of fields throughout the file.
