UC20 only uses predictable names. It is intentional to use stable names.
There is nothing in the gadget about it. But rather kernel drivers, dtb,
udev.
eth0 name is a bug. And it means udev failed to establish a predictable
name for it.
I think we either need to add an additional policy file for it, to at
least use mac based name and/or work with kernel & upstream to
positively identify it.

Title:
UC20 images do not use predictable interface names on RPi4

Image tested: http://cdimage.ubuntu.com/ubuntu-core/20/dangerous-
beta/pending/ubuntu-core-20-arm64+raspi.img.xz
Boot the image and check the naming of the ethernet interfaces. On
most devices (amd64, rpi3 etc) systemd predicatable interface naming
is applied e.g. enxb827eb7d1eee. However on specifically RPi4 devices
traditional naming is used e.g. eth0, eth1.
