Even Unicode doesn't go so far as to decompose WITH STROKE.
In fact, I would argue that the COMBINING HORN was a mistake. It would
have been only slightly less efficient to include O WITH HORN and U WITH
HORN (uc and lc) as undecomposable letters; HORN is really not a diacritic
but a modification of the ordinary O and U.
