I think such a command should check all heading data by default,
because that's the safest option. A user who commonly needs to ignore
one or more types of data could use a custom function that calls the
command with arguments to disable checking of certain types.

I think warning or asking for confirmation should be the default action,
because it's the safest option. Users who want to skip that could use a
prefix argument or call it from a custom command.

An example where this would be useful is if the user has copied and
pasted subtrees and accidentally pasted one more than once.
I argue here for the safest behavior by default because I've found that,
in very large Org buffers, it's easy to lose my place in the file, and
it's easy to accidentally do something that I didn't mean to, without
noticing. IMO this is simply a consequence of Org buffers still being
plain-text.
So it is quite conceivable to me that a user might intentionally give
two headings the same name (e.g. a user who captures quotations to an
inbox file might have two "Quote" headings that are completely
different), or might accidentally duplicate a subtree and then make a
desired change to one of them without realizing there was a
duplicate--then he might use this deduplication command and accidentally
delete a subtree he didn't mean to, resulting in data loss.
