Hi @riyadparvez, we don't have any immediate plans. We do have a tutorial notebook on using CMA-ES to optimize acquisition functions in BoTorch, but haven't had any use-cases for zeroth-order optimizers within Ax itself. Our goal has been to accelerate experimentation in cases where experiments are costly to run—so our focus has been around algorithms that perform well with less than a few hundred iterations.
What use-case did you have in mind for population-based optimization with Ax?
That being said, it should be fairly straightforward to add a model bridge for Nevergrad.
If you do end up putting something together, we'd be happy to review any PRs and add it to Ax!

We will now be tracking wishlist items / feature requests in a master issue for improved visibility: #566. Of course please feel free to still open new feature requests issues; we'll take care of thinking them through and adding them to the master issue.
For this specific issue, there is currently ongoing work that may address it; we will make sure to comment here if/when the prospects become clearer there.
