I say a patch shouldbe made to at least detect irregular Pokemon data.
Also is it me or is the name Bad Egg rather convenient?
It shouldn't be that hard to do, really.. It's just more effort from them (especially since the games already out, to completely change the whole way the wonder trade/w.e else sorta training works). It's not as simple as just chucking some code in the middle of the script of the trading aspect, you'd need to change a lot more to get the validation to work, I could be wrong).
