Yes. T.61 is still in use. It uses combining accents. One place where it
used is in X.500. It also have the nice way where the combining accent
comes before the base character making it easier to parse.

NFD should not be an extension of ASCII. There are several spacing
accents in ASCII
that should be decomposed just like the spacing accents in ISO 8859-1
All or none spacing accents should be decomposed.
I could ask why are not precomposed characters preferred to be used, if
For a lot of text handling precomposed characters are much easier to
when the combining character comes after instead of before the base
