I am a Fedora user and contributor. So Debian goodies, as you call them, will be replaced by Fedora goodies. There is nothing that Fedora does better or worse than Debian. Each one has its idiosyncrasies. I do find RPM packaging easier, but that's only because I know it better. As for /etc, it's about the same, Fedora network config is in /etc/sysconfig/network-scripts.

Despite this, I also concur that is does not make much sense to move from a Debian-based system. First, because it worked well and Maemo in this form has matured. Second, as someone pointed out, the lack of maturity of ARM-based Fedora.

But, again, this has nothing to do with inherent quality of both distributions. There are many things that I like better on Fedora, and some good ideas from Debian and Ubuntu have been integrated into Fedora.
