warnings on outdated specs/docs

The w3c has literally thousands and thousands of versions of the many specs
that are produced, Every outdated document is a source of possible error,
confusion and misinformation for consumers (of all types) of this
information.

Some adhoc attempts to mitigate the issue has been occuring by individual
editors and working groups.

Is there a  consortium wide policy to have warnings and associated clearly
labelled links to latest versions on documents that are stale? If not can
we make this a thing?
