Unfortunately, I couldn't find any information on a "haste breakpoint" product specifically related to Feral Druid in the provided search results. However, I can suggest some possible alternatives to help you achieve your goal.

One option is to use the flow-api-translator toolkit to create a Flow source code that includes haste-related functionality for Feral Druid. This might require some manual coding and configuration.

Another option is to explore other libraries or tools that provide haste-related features for Druid, such as jest-haste-map. However, without more specific information on what you're trying to achieve with haste breakpoint, it's difficult to provide a more tailored solution.

If you have any further questions or clarification on your requirements, I'd be happy to try and assist you.
