 Currently, it seems that Tor clients don't use DA nodes for construction
 of circuits because all DA's bandwidth is set to 20, which is a very low
 value. To move unneeded client traffic out of DA nodes completely, we
 could have some `torrc` option on client's side (which disables
 construction of such circuits) and on DA's side (which block client's
 requests to use the DA as a node in its circuits). Additionally, use of DA
 nodes in clients circuits may be governed by some consensus values
 published by DA nodes.

 In general, in testing Tor network with a small number of nodes, enabling
 this option may be undesirable, but in the main Tor network it may help DA
 nodes to decrease their load. Also, this explicit solution may be more
 clean than the current probabilistic approach which relies on a small
 bandwidth value set for DA nodes.

 This task was originally discussed in
