I honestly don't care. If I ever made a competitive team I for one wouldn't bother wasting hours of my life breeding for IVs if I had alternative methods available. I wouldn't expect anyone else to either.
As far as I'm concerned, whatever's within the game's determined limits is legal and fair play. Wanna throw out a shiny pokemon with 31 IVs across the board, good nature and all its good egg moves? Go right ahead. :\
