Hello , that maybe would not be a problem , if we would have a list with all airlines in game. But this we not have ! Ok , we have parts of it , but not all. If everyone would also upload his mods also in a singlemod we would be able to see that very easy in the steam workshop. But here are many Mod packs. (That is no problem , but then it would be good to have a list with all mods inside. Some have that , some not. That is the problem. But i think also if we have a good overview there will be created some mods twice , because the modder for example wants a better livery , or a other plane etc.
For me the most importent is to have fun , and if someone wants to do mods again , it is complete ok for me.
