That's exactly how I've been using it, and it works much cleaner than other solutions I've tried.
The new edition of the Camel book says for each, "Deprecated, do not use in anything new." It sounds more to me like calling the use of 'our' deprecated was a mistake. It should have been given a better message about being reserved for future use. Deprecated has always meant to me that something had been superceded by something better (safer, faster, etc) so you should transition before the feature is removed.
Just my .02
