But that fixes the IP addresses both to my local network. The intended
NM approach was to allow the virtual network interfaces of virtual
machines the chance to pick up an IP address using DHCP whatever local
network they're on.

That would seem to conflict with this:
http://www.linux-kvm.org/page/Networking#public_bridge (Debian's way)
(notwithstanding it was published some time ago and not by a
Debian-focused organisation, but still, it's documentation...

Hmm. Kinda doesn't fit the use case then

Because I have a multiplicity of networking requirements on my laptop.
I need VPN access, easy wireless configuration, and the ability to run
virtual machines with IP addresses on the local network (wherever I am).

Agreed. A conflict doesn't necessarily mean a mutex. That was just
what I was inferring, reading between the lines and all that...

My experience is becoming more like yours in Debian .. but less like
yours in Fedora (sorry, I said the F-word!).

Would this second interface have to physically exist?
