In Hermione's case her 'characteristics' were intelligence and wild hair.
While race per se shouldn't be a defining characteristic we do have a reasonable idea of what she looks like from the movies. Coming close to this look is to me part of the character, one should avoid casting people that look nothing like the established pattern.
Why should the casting choice of the first movie have anything to do with anything?
Was race or a particular look an integral part of the original story? No.
