I don’t mind it either.
There’s been a fair few Princesses of Wales and Queen Catherine’s. So I’m fairly sure it’s how she’ll be known in history - no different to Elizabeth Woodville, Anne Boleyn, Katherine Parr, Wallis Simpson, Sarah Ferguson etc - women who have married into the royal family and had surnames are generally still generally referred to by those names.
Women who married in with titles are generally known by that too - Charlotte of Mecklenburg-Strelitz, Anne of Denmark, Princess Mary of Teck, etc.
