Description
Summary:
having init_r counterpart in optimizing can be helpful.
Description:
Random initialization is sometimes too strict in optimizing routine, having the init_r counterpart as in sampling might be helpful. I think cmdstanr has it as mentioned here.
Reproducible Steps:
Cannot initialize some optimization.

Research direction
Start by comparing the public optimizing and sampling interfaces, especially how sampling exposes init_r. Then determine the intended initialization API and its behavior when optimization cannot initialize. Done means the optimizing interface supports the requested initialization counterpart with coverage for the reported failure case.
