Proxying watchOS without macOS proxy?

Proxyman's documentation seems to imply watchOS proxying should work, but it's unclear whether it's possible to proxy watchOS directly or whether you have to have the macOS proxy enabled. I need to proxy watchOS without the macOS proxy, as the macOS proxy is blocked by corporate security software. However, configuring URLSession in the watchOS sim to use a ProxyConfiguration seems to have no affect, for any proxy type. Nor does running the watchOS app and the iOS at the same time make any difference. The iOS traffic is properly proxied, but nothing from watchOS shows up. Is this possible?

Barring that, is it possible to configure Proxyman to act as a passthrough server, like you can Burp Suite, where a request to localhost:8080/myapi/resource is forwarded to the proper root domain? Seems like a rewriter might be able to do it, but the question is whether I can make a directly request to Proxyman in the first place.

Start by checking Proxyman's documented watchOS support and the watchOS simulator's URLSession ProxyConfiguration behavior; the issue names no repository files or tests. Compare direct watchOS proxying with the proposed localhost passthrough and rewriter flow, and consider the work done only when one supported configuration or limitation is clearly established.
