If you are managing 1 or 10 that are not the same, then yes, but if one is managing 10,000+ physical linu servers with a very few models/layouts (spanning the 5-9 year life you are dealing with) and you up front determine the mappings by model then by pcid mapping is great.
Prior to the pciids naming scheme, it depended on the order the drivers were loaded, and if you added the cards after the fact it showed up after the current cards (udev rule mapping by mac address and/or mac address mapping in ifcfg files). And if you involve the mac addresses anywhere replacing any failing hardware becomes a complicated process, as you have to find the udev rule/ifcfg-hwaddr and fix it, and if the node was dead when you do the replacement one has to often take it to single user mode and sort out the mac addresses. With the pciids, then replacement with a like identical replacement is easy, as the new machine just boots up and works, with mac addresses, it does boot up, but the network fails and has to be manually fixed. And when one is managing a bunch of systems this becomes a problem, the pciids also result in the configurations of a like model all having the exact same names for the same physical cards at the same locations which make things much simpler for the automation building systems and the people cabling the systems.
