The API returns a list of fi_info structures on success or an error.  This could be changed to:

- Return fi_info structures even if an error is returned
- Return multiple error codes + fi_info list
- Carry error information as part of fi_info
?

It's a matter of complexity being exposed to the user.  We've also discussed adding runtime options to disable built-in providers as a work-around for buggy providers.
