I agree with you completely and I even developed an open -source writing system called Eskéndereyya [1] to help learners of Arabic in reading and pronunciation and to prepare them to make the jump to the Arabic script very confidently because I noticed that some beginners are put off by the notion of learning a completely new script just to read and write few sentences and when taking into account how usually Arabic is communicated in writing without diacritics, it becomes very frustrating for them to get any immediate return for their efforts to learn the language.
