The problem is that it makes configs and logs unusable for the
purpose of tracing typos and dump misconfigurations like proxy
loops.

General recommendation for those who don't want to show names and
ips in public is to reporoduce a problem in some test environment
instead, and provide real configs and logs from this environment.

Most trivial test is to do something like:

$ time curl -o /dev/null http://example.com

to see if it show the problem (i.e., if it's slow, and how slow it
is).
