There's the problem that "appears" is a visible phenomenon and unicode strings can contain non-visible characters and multiple ways to represent the same visible information. Normalization is supposed to help here, but some sites may fail to do this or do incorrectly, etc.

But the MRZ of a passport doesn't contain any of those problem characters.

But on some random website, with people copy-pasting from who-knows-what, they will have to normalize or validate, etc. to deal with such characters.

The point is if the standard were to enter it like in the MRZ, it would be easy to validate.
