Is there any guarantee that U+E4567 will not have a canonical decomposition mapping to <U+0F73 TIBETAN VOWEL SIGN II, U+E4568>? If so, where is it published? I thought we had guarantees that new canonical decompositions to non-starters would not be created (to <U+0F71, U+0F72, U+E4568> in this case), but I cannot find it. This conceivable decomposition mapping appears to wriggle through a loophole because U+0F73 is a starter, i.e. has canonical combining class 0.
