The smart solution would be to expire these objects out of the cache reasonably rapidly.

There's an unfortunate amount of software that uses filesystem polling as a crude form of IPC. Check every x seconds to see if a file at a certain path exists. Fast expiring these dentry nodes would hurt that workload.
