Comment (by teor):

 Replying to [comment:20 dgoulet]:
 > 1) Do we want to do it for current v2 HS version?
 >
 > Personally, I don't think we need this for v2 as the improvement that
 this line will give us is more on the UI/UX side of TBB for instance which
 could take a while to get in and by that point will have prop224 not far
 from done.

 I can't see any direct benefit from this, as we are not doing the relay-
 side mitigations in 0.3.0 as far as I know.

 > Also, we would have to make _sure_ that clients won't explode with an
 unknown line in the descriptor and HSDir will also accept it as they do
 parse the descriptor for validation.

 I don't think it's worth the risk.
