I mean more like renaming them on the fly --- or by having a configuration file with key:value pairs like 'enp69s0f1:eth3' --- or perhaps triples like 'enp69s0f1:eth3:"DMZ Interface"'. That way, you could have a recognisable name (or several names) for every unrecognisable one and assume that "eth3" or "foo" or however you want to call it is the same interface just as much as you would with unrecognisable names --- plus the advantage that when you ever need to change an interface, you only need to edit one small file rather than various configurations files having the unrecognisable name(s) in them. And you would also have descriptions.
