Governments about which we are talking have methods to filter
particular images, not just domain names. But, I am fine with
.../safe/ as an option.

The other issue is that those who want to censor actually want to
block non-censored access. If so, let's them give that, but not on the
main site, so they could actually block en.wikipedia.org if they are
so insane. Bottom line is to protect more permissive cultures. If some
group really wants to have Wikipedia censored and it's so powerful to
push WMF Board to do something beyond reasonable involvement in
content issues, sexual education of their children is around the
bottom of my concerns.

I am not sure what do you object at the end. If you have better
technical idea or have an idea for better design, I am fine with it as
long as it doesn't affect the main site.
