Great post! I was really looking forward to using Gutenberg in Drupal, but upon finding wp in the block classes was disappointed. Maybe it's just me but it feels dirty to have those WordPress identifiers in Drupal. You definitely list A LOT of advantages to using it though!
Thanks for the comment.
You see the wp classes because it's using the Gutenberg blocks that ship with the plugin.
I guess the solution is to just create your own set of blocks. :)
