You're right. But I have to think about the efficiency of writing it. "ы" takes up more space than an "і".

And "ы" originally means "ъ" and "і" combined together, so "ы" is actually the same as "и". Turkic ı represents a completely different vowel. The letter ı was created during the Atatürk reform, over 1000 years after the creation of Cyrillic. That's why I don't want to use "ы".

And how about iotified "ы"? We have я, е, ё and ю. Unless we take the iotification out and thus uses a new letter "j".
