What's "important feature" for you is completely irrelevant for a lot of users that only want to send a text message. Whenever something else than plain text happens in my message is not only unintentional (I didn't even want to press the stupid button) but can incur high costs to me or my correspondents by my or by their phone company (neither all the world has the same contracts nor uses iMessages the way you do). Having a bunch of buttons near the text field of a message to be sent that can be accidentally and easily hit is an UI fail for anybody surely not needing that bunch of buttons. You can show them to those who need them but you should let others protect themselves from them especially in the app that can result in sending SMS or MMS which can be expensive.
