There's a counter example of precedent for the German umlaut which was
unfortunately unified with the diaeresis, even if its origin (and still its
current semantic) is that of a combining letter e and where it does not
play the phonetic role of a diaresis (i.e. the separation of two vowels to
avoid creating digrams for a single phonem represented by pairs of letters).
So "ä" in German is cognate to the "ae" digram, similar to the "ai" digram
used in French (or to the "æ" ligature used other languages, sometimes as a
distinct letter of their basic alphabet), it contains no phonetic diaeresis
as there's a single phonem, and no diphtong (like "aï" in French where this
is a true diaeresis to break the interpretation as the digram "ai").
Same remark for "ö" in German cognate to the digram "oe" (or the ligatured
letter "œ" in other languages or the variant "ø" in Nordic languages), and
"ü" cognate to "ue".
But Unicode just prefered to keep the roundtrip compatiblity with earlier
8-bit encodings (including existing ISO 8859 and DIN standards) so that "ü"
in German and French also have the same canonical decomposition even if the
diacritic is a diaeresis in French and an umlaut in German, with different
semantics and origins.
