Setting that parameter should work, but it doesn't take precedence over
an existing /etc/udev/rules.d/70-persistent-net.rules

Since net.ifnames=1 is the default since stretch, you don't need to set
it explicitly though.

Most likely the file /etc/udev/rules.d/70-persistent-net.rules got
embedded in the initramfs. So once you removed that file, you also need
to rebuild the initramfs via update-initramfs -u
