Comment(by rransom):

 Reasons to keep MyFamily include:

  * If someone administers many relays, they are likely to all have similar
 configurations, so there will be some attacks which compromise all relays
 in a family and would not compromise unrelated relays.
  * If someone administers many relays, he/she/it may want to reduce the
 amount of traffic which his/her/its relays could potentially correlate, in
 order to reduce the value of performing a rubber-hose attack.  (But this
 doesn't work so well if people don't pay attention to MyFamily or if relay
 operators suck at setting it.)

 More reasons to throw away MyFamily include:

  * The current implementation takes up a lot of space in relay
 descriptors, and presumably also in microdescriptors.
  * Adding a better implementation will take a lot of developer resources,
 and in particular, it will take a lot of my resources if you want to go
 for the 160-bit elliptic curve (rather than using the Curve25519 group and
 spending 512 or 768 bits per signature).
