Users are free to avoid loading certain control algorithms from the json tuning file if they wish, and this could mean that some libcamera controls will therefore not be available. Currently we don't have a good means of indicating which these are, therefore failing completely when an application tries to use one is unhelpful - it is better just to issue a warning. Note that once we can indicate this properly, applications should check for supported controls as this change may be reverted.
