Hm, the way we've been thinking about this, the SR doc is only useful to dirauths. 

I don't think that directory mirrors or clients will ever need to download
it. So I think we will indeed need to mod that code to skip the SR doc if we are
not dirauths.

Of course, SR docs should be puclicly available so that CollecTor and
ConsensusHealth can fetch them and analyze them.
