asset.maxAge not applied with `fallthrough: true`

Looks like when fallthrough: true, a publicAsset's maxAge property is not applied, so no cache-control headers are added.

Is there a way to go around this. I need fallthrough: true because I want to server the /public dir at / base. But imagine i want a route rule too apply to all the public assets at /**, (but not the cases which fallthrough to a lower handlet). Is this not possible right now?

As I can see, it uses defu to apply defaults to provided routeRules. You can still pass in your own routeRules with the required headers. See: https://nitro.unjs.io/guide/routing#route-rules

please provide a minimal reproduction 🙏🏼

I think the easiest way is to explicitly add routeRules entries for asset path cache headers. (nitro cannot safely assume to apply headers to paths that can fallback to other handlers)
