 proposal 247 with a new proposal for mesh-based vanguards, so we can keep
 the old proposal text around.

 Good stuff. I agree with the new proposal idea.

 I was not sure where to comment, so I started a new PR and commented
 within: https://github.com/torproject/torspec/pull/9/files

 Things look pretty good and as expected.

 I was mainly surprised about the introduction of the max(X,X) distribution
 which was not discussed in the past months. I wonder what it offers. To
 better investigate it, I added a new commit to the vanguard simulator that
 implements max(X,X).
