I'm used to leverage Bundle Copy to import/export content types with Drupal 7. One of my expectations with Drupal 8 is that I could theoretically achieve this with CMI. On the Bundle Copy project page it's also mentioned that "Bundle Copy is in Drupal 8 Core CMI!" so it all looks promising.
However, due to UUIDs and CMI's focus being on supporting content staging across multiple instances of a same site, it doesn't seem that obvious to create a generic content type that you would export on N number of sites.
For instance, take a photo gallery content type. Once you've created it and that you're happy with everything, you probably don't want to go through the same hassle again and would likely prefer to simply import the YML files onto the active configuration dir via CMI's single import tab (by manually copying the content of your YML files) or via the Synchronize tab (by making YML files available under the staging dir).
I thus wonder if a) I've missed something and b) if yes, what's your recipe for portable content types, if any?
