  ## Feature Request Type
  
  - [x] Core functionality
  - [ ] Alteration (enhancement/optimization) of existing feature(s)
  - [ ] New behavior
  
  ## Description
  
  <!-- A few sentences describing what it is. -->
  It would be nice to have builtin strawberry utilities that perform schema check functionality like graphql-core's [find_breaking_changes](https://graphql-core-3.readthedocs.io/en/latest/modules/utilities.html#graphql.utilities.find_breaking_changes) and [find_dangerous_changes](https://graphql-core-3.readthedocs.io/en/latest/modules/utilities.html#graphql.utilities.find_dangerous_changes).
  
  Note: this functionality is currently achievable by using the Strawberry export tool into GraphQL SDL and then running the graph-ql core function.
