@Riot - Could we get the Ashe Flurry update on other champion abilities?

http://www.surrenderat20.net/2015/06/62-pbe-update.html

With the change on Ashe's Q that "This flurry attack cannot occur on structures", could we see that on other champions' "on hit" abilities as well? Most experienced players know that Nasus' Q WILL hit a tower, but why NOT Darius' W? What if I don't know if a modified auto from Viktor (after he uses his Q) will hit a structure? This is a clarity issue that I would love to see improved on. :)
