Do these relays set "dir-cache 0" in their router descriptors? Or do
they just not include "dir-cache 1"? But if they set a non-zero
DirPort, how will the directory authorities and clients know that the
node doesn't want to act as a directory cache?

What are the rules when setting a DirPort? Successful self-test and
minimum advertised bandwidth? How's "1" different from "auto" if Tor
decides whether to act as a directory cache in both cases?

Would it make sense to have them assign the "DirCache" flag for nodes
with a non-zero DirPort, too?
