That probably makes sense, though I still feel it is a little inconsistent.
One could argue that anything within colons is an org tag (regardless of
whether the title is empty), and isn't meant to be exported. It's probably
rare to start a headline with a colon anyway.

Plus, I guess you are still somewhat restricted if you want to export a
headline ** foo :bar:, where :bar: is not a tag. ;)

In any case, there are workarounds available for what you have to do.

Yes, either way works.
