Let me "change my tone" on this "one" bit:
Example: en.wikipedia.org/wiki/America_Invents_Act
Let say I want to know if that page has any warning tags. If they just raise 203 when that page is tagged, then that gives the status of that page with the tag raised. Does wikipedia have standard warning tags; how long did it take for you to figure that out across all wikipedias in each language for that page; do they all agree; who else agrees on how long that took while indeterminate; who agrees on the last known version of that page while OK; the GFDL helped in the issue that wants only to verify the first and last version as the cover pages; historic digital signage exists with "authorized-information".
If 203, save your breath... ... about "doing normal" 200 things.
Would you ask your client for their password when you know that status code is 203 and not 200?
