A while back it was possible to do it by a rule file, now there's the
need to add it to the kernel command line. From the beginning I didn't
waste my time and simply migrated to the new bizarre names.

I'm using

  basename $(ls -d /sys/class/net/enp?s0)

for my scripts. If I remove or mount PCI audio cards, not at
runtime, just after the PC powered off, the number of the integrated
network device changes with the next startup.

So I for example use

  dhcpcd $(basename $(ls -d /sys/class/net/enp?s0))

this works, as long as you only have got e.g. one on-board device. For
me the ? works, but perhaps using a * is better.

If you have several devices, or you connect and disconnect USB
network devices, it's likely more tricky.
