I see this feature as primarily being useful on lists. So for example:
* Things to buy
** cabbage
** milk
** carrots
** milk
I don’t know if a more intelligent way of handling tags and todo
keywords is worth the extra complexity, but in the use case that I
imagine it makes sense to match using only the heading/list item:
* Things to buy
** TODO cabbage
** DONE milk :store1:
Maybe I forgot a tag here. Oh well, I already bought the milk.
** TODO carrots
** TODO milk :store1:store2:

Since the point would be remove duplicates from lists, I don’t think
warning is very useful. I would want to remove the duplicate list
items, not get a warning about it and delete them manually. Perhaps
that would be a useful additional feature however (like uniq -d).
It doesn’t make sense to include the contents because I see this as
primarily being useful for list items. In particular, we would want
to ignore log entries and properties for the sake of matching
(intelligent property or logbook merging might be useful, but adds
complexity).
I don’t think doing a full text check is useful, but if someone has a
use case for that, please speak up.
