Why did you guys remove error features in Functions

I don't see how Functions are an improvement over Callable recipes.  If you hit an error in a Callable recipe you could respond back to the parent with the error and the error message.  The parent would see that and mark the parent as failed.  Why did that get removed?  This makes errors a lot harder as we now need to do a lot more to create an error.

BRING BACK ERRORS.

ALSO IT DOESN'T SEEM LIKE YOU GUYS READ THESE.

Good point. Already reported this as well. Really REALLY important to get error catching blocks and error handling in general working properly in functions! The dev team is aware, though, and working on it, I was told.

When will this feature be put into place?  Why did you guys roll out functions with this being left off?
