Unlike all the features you listed, text wrapping is commonly found in vector drawing programs (See Serif Draw). Also unlike all the features you have listed, the absence of text wrapping seems to be a issue of a lot of AD users: Link! To quote the page you linked:
The bolted words are projects where text wrapping is really useful or even necessary. Also, if I understand your opinion correctly, you think I need a full fledged DTP program to design a single poster with some text on it? Sorry, than I am disagreeing. Btw, I really like AD, I bought it even just because it really cool (and cheap). And with text wrapping included, many people, including me, would be much happier.
