Not in Latin-alphabet text generally. Writing systems that have
such needs include Vietnamese, IPA, Math, Polytonic Greek,
Biblical Hebrew and Talmudic Aramaic, Quranic Arabic, Syriac,
and all the writing systems descended from Brahmi (Indic, South
Asian, Tibetan, Mongolian, and a few others not yet in Unicode).
Indic and South Asian are much higher priority than multiply
accented Latin for mathematicians.

Exactly right.

Not for math. Talk to the experts at SIL about the Asian writing
systems and IPA. They have defined a new table for OpenType
fonts in order to handle Burmese and some other scripts.
