Supposedly they're coming, but I don't think they're officially there yet (except for some big brands)

Now you might already have a personal one, if created a Google profile (back when they still had them) with your name in it; I do.

In the short term, I just made a redirect off my own domain - example.com/+ - for it.

You could check [gplus.to...] for an 'unofficial' but quite elegant custom url

True, but if the end goal is to establish some kind of branding on Google+, I'd think you'd want to use your own name if possible.
