The specific example you offered, BND and VBLTX, is inapposite for the purpose of this thread. Those two funds are not even in the same asset class; one is an intermediate-term bond fund while the other is a long-term bond fund. As such, they are clearly not "substantially identical".
Below are screenshots from Vanguard's SP500 Index fund ETF and mutual fund. Good luck determining which is which based on the top ten holdings (which are identical to the share all the way through the funds).
