It might be true to some extent but I don't think it's a complete deal breaker either. Look at Cyrillic print fonts for instance, the lowercase is effectively what we would call smallcaps in the latin alphabet: здравствуйте ЗДРАВСТВУЙТЕ. The р and у do deep lower in lowercase, but that's about it. I really think it's a matter of habit and tradition more than anything else.
