Log with id-s and/or location of the detected/expected problems may be
helpful and probably easiest to generate without complicating the
redaction script too much.

The tag sounds like a good idea, but it has one problem: untouched tags
would stay forever even if there is no real problem there. It will be
only unneeded data in the database. Of course, the tags could be removed
by some bot later… but we don't like bots, do we?

Sounds like an extra work for the people who already have much to do.

With the logs or the tags anyone can make use of the data and make tools
(visualisations) to handle it.

The data from the logs could be overlaid over any OSM rendering, tags
can also be overlaid or rendered with other data.

Would these tools catch all of the problem you mentioned?
