I think '-i, --interactive' was more of a proposal what option is needed than
feedback how use command. Currently implemented options are below.

Unrelated to this request there's been times when I wish tar would have a
way to 'extract' only meta-data, such as permissions and ownership, but not
update file content.  This would be handy when wanting to recover from
accidental sudo chown -R /usr/ run or something of that sort.

While on it being able to create tar file that contains only meta info would
make permission revert quite interesting, and hopefully lightweight. But
that is a totally new file format and miles away off topic what was requested
originally. So let me add my two pennies to that discussion.

I am not a maintainer, but I don't see any problem adding --interactive long
only option. Getting a short option may clash with future posix requirement,
so I believe they are not handed out without really good reasons.
