There are some people suggesting that, however at a small scale and not taken that seriously by many. What difference does it make? What about all the other words that underwent the sound change? Also, some nuanced people can keep languages and politics separate. The sound shift isn't even entirely clear to be due to arabic influence, how come it turned into 'f' and not 'b' such as the arabic approximation? How come sounds like 'g' remained?
And in the end, in English it should be "Persian" and not "Farsi", that is where the actual move should be. How sad and historically wasteful if we started to do that to all languages, "deutsch", "zhongwen" or "elliniki" instead of German, Chinese and Greek
