6 years ago Polymer 3.0 being still in preview mode, i don't think publishing a version for it will be much useful. But having said that, having a separate branch for it and adding about it in documentation is not such a bad idea.
But i think i'd like to wait atleast until rc (release candidate) version of 3.0 comes out.
Not sure how (or if) you want to handle this, but I've converted image-carousel to Polymer 3.0 (pre-something). Right now, it's internal to the app I'm developing (works fine), but I can put it on a branch and create a pull request, if you'd like. If not, no problem :)
