How limit access to a paragraph type by role, like it is for content types? The permissions page at /admin/people/permissions provides very fine grain control over which actions people can do with specific content types. How can I  add all paragraph types under this permission system? We have a paragraph type that is reserved only for special cases, and we don't want anyone but a certain custom editor role creating/editing them.

I've searched for a few contrib modules, but many are not updated (or just plain abandoned) with little documentation.
Simply enable the Paragraphs sub-module Paragraphs Type Permissions. It provides CRUD permissions per Paragraphs Type.

  Allows users to configure permissions for individual Paragraphs
  types.
