No, everyone involved will know that they screwed up.
The system performs perfectly well with other big users, so there is no reason on earth that it should not do its job at EK, apart for the additional BS they (he) put in.
It costs a lot of money and if it does not perform, guess who will get the bashing?
"He" won't, he can do nothing wrong for the obvious reasons we all endure in the pit, the system can't be blamed as it works well with all other users. That leaves only one or two poor pawns below him.
Any attempt to blame it further down the food chain would be futile.
They know it, Jep knows it, we know it and that is the reason good old TCAS is panicking with this fourth letter!
