Yes, something similar should be doable (and desirable) for Windows. In fact, that makes me think whether we should generalize this option to something like --with-external-debug-symbols-in-product-bundles=<full|public>. So, that way one could decide which PDBs to ship and it could eventually also be made available for other platforms and external debug symbols. And jlink plugins could then handle this and remove/strip this information.
