You mean the impact (in terms of lower performance) of handovers across
3GPP and non-3GPP handovers does not really matter because those
applications that rely on high performing handovers will anyway not rely
on such?
But you could make a case that we could see applications (eg. Skype) that
would benefit from lower latency handovers across the different radio
systems.
