For PCIe, that's only

Can device and function really change? My understanding is that device
part is determined by bus physical wiring and function by PCI card
design; this leaves bus as volatile

Well, different naming strategies have different advantages and
disadvantages. If you use the MAC address, then replacing hardware
becomes harder, and you can't cover hardware that doesn't have fixed
MAC addresses (or VMs)

For example, in one of those tests I initially had this setup:
Integrated NIC: enp9s0
PCIE1 (x1): dual port ethernet card [enp3s0, enp4s0]
PCIE2 (x16): empty
PCIE3 (x1): dual port ethernet card [enp7s0, enp8s0]
Then i inserted a SATA controller in the PCIE2
