 * I’m wondering if your blocks are extendable using a methodology like this:
    [https://developer.wordpress.org/block-editor/tutorials/javascript/extending-the-block-editor/](https://developer.wordpress.org/block-editor/tutorials/javascript/extending-the-block-editor/)
 * My use case here is the ability to add a capability to your container block to
   allow for fixed-position backgrounds or full-height backgrounds. I can write 
   CSS to make either of those work without changing any markup, but I want there
   to be a button to click to add the class to the section to make it work (rather
   than trusting that the end user will remember the specific class names to use).
 * If there’s another method I should be looking at instead, I’d be interested to
   see that as well!
