Lamassu, Actually I'm the local here since I live in this city, in the eastern part of Baghdad City to be exact, while you live in al-Mahmudiyah town south of Baghdad City. We both know this fact and established it previously. Same goes for the user desertivy, who live in al-Ma'aml, north east of Baghdad, outside the boundaries of Baghdad city https://www.openstreetmap.org/relation/5638803.       
     
And, for us, the locals, in the city, we always call it by it's name for me and the people I know. Some might call it by it's number, and that's not wrong. We shall not name it by it's number, it shall be by the actual street name that is over 50 year old and still officially used as proven above in the map by Baghdad Municipality. It's not changed to "Street 77" as a name. So, at the end, name of the street in 'name', number of the street in 'ref', and also no harm to have it in 'alt_name' if you insist that the street number can be treated as a name.          
     
Here is a map of Baghdad from Baghdad Municipality showing the street name: https://amanatbaghdad.gov.iq/ar/news/9d116041-df40-4f38-837d-666b24a22743 and also your friend, the user 'desertivy' have many other official maps made by the Baghdad Municipality for the neighborhoods, it was givin to him by a guy who work at the Municipality, and all of them has the name "al-Ameen Street".    
     
Now, I'm gonna change the name of the street to the short name without the full name of the subject as per the notes of user 'desertivy'. Keep in mind there is the same full name for other streets in Iraq in other cities, for example in Karbala https://www.openstreetmap.org/way/665891734 , I will not change that.     
Regards.
