Links with link-local-only communication are typically peer-to-peer links between two laptops or similar. In such cases it makes sense to be able to see which device one is specifically connected to, hence let's just enable LLDP for it. This doesn't leak any data really, given that this is inherently local, and typically only used between isolated systems that are under the same user's possession. Background: I recently connected multiple laptops via thunderbolt networking and was kinda annoyed not being able to see what system I was actually talking to. (Also, the file touched here is an example only anyway, so even if this would leak too much info, it's not in effect by default)
