The problem is not so much non-Arabic speakers having difficulty dealing with the language, since they're not really the target audience. But if an Arabic speaker tries to use this language to write a program for some specific use case they have, they'll have to work around the complete lack of ecosystem that comes with a novel language in a tiny niche.
It's the same reason why Chinese developers haven't banded together to create a Chinese-based language. They still code in Chinese, but the languages and libraries they use are mainstream: C++, Java, Python, ... All of these languages support arbitrary Unicode in comments and Java and Python also support Unicode identifiers. As a result, Chinese documentation is available even for software that's otherwise in English. However, if you tried to convince Chinese developers to abandon their battle-tested languages with a rich ecosystem for some other language just so they can use different keywords, you'd get laughed out of the room. It's not solving a problem they have.
That doesn't mean that localized programming languages can't be useful e.g. in education. But translating documentation and libraries is useful for many more people than translating the syntax of a language.
Yes. Any new programming language needs to offer something more than just different syntax if it wants to be used by more than just a handful of people.
