Just a little remark:
I lately had discussions with content providers who could perhaps 
release their content under a free licence, and I needed statistics on 
Commons. Templates and categories are really helpful there, because one 
can extract statistics from them through SQL queries.

For instance, after some SQL work, I was able to count the ratio of 
articles on astronautics on Wikipedia in French that have PD-USGov 
illustrations.

In contrast, textual explanations and other things that should be 
reviewed by a human do not help.
