Do you have examples of this? I wonder if it's implementation specific or due to the NFKC method itself?

  The issue does not have anything to do with normalization per se, but stems from the fact that there are Unicode characters that are semantically different, but nevertheless look exactly same in most fonts. For example 'a' (U+0061 LATIN SMALL LETTER A) vs. 'а' (U+0430 CYRILLIC SMALL LETTER A)

    It's probably also futile to keep homoglyph tables without the context of the font being used, as т and т are the same letter, just with different styles (and in some fonts resemble T and m respectively in Latin). Unicode mentions homoglyphs briefly in UTR #36, but overall I feel that it's not really their job to solve that issue, as visually similar characters already exist in ASCII and other limited character sets and every context where those things are a problem probably needs to be evaluated differently with different mitigations.
