One problem with biosdevname is that it uses different naming schemes

lspci or DMI information of your card you can deterministically figure
out how your network interface is going to be named, but also the
reverse, that by looking at an interface name you can figure out where
precisely the data came from. With biosdevname' scheme you cannot do
that as using different enumeration within the same namespace might
result in name clashes, and hence we think it's a good idea to stay away
from the old namespace.
This has a flipside: devices are likely to have similar names regardless of
hardware details. This makes it easier to manage heterogeneous (i.e., real
world) datacenters. That's not a primary use case for Fedora, but it sure is
for our downstream distributions.
