Mh. I really cannot understand why you argue against it????
It would be only visible for those using the gunsight view (shitf+F1) while all others happy with leaning to the right side would just continue leaning to the right side. So you would still be able to play as today while the others who would like to use the gunsight as it was used in real life can use it in a manner how it was used in reality - be it ugly or not. Reality is not defined by its ugliness or beauty nor do movies define what is reality and what is not.
And please don't try to censur people expressing their wishes, ideas and proposition by telling them basically to shut up just because you basically think other stuff is more important (may be only important to some of you). I think the devs know in which order they have to sort out things.
