`withoutActuallyEscaping` and `@isolated(any)`

Using Swift
3

I've recently stumbled across this error:
withoutActuallyEscaping is currently unimplemented for @isolated(any) function values .

First of all, is this something than can be expected to work in the future, and if so, is it worth filing a bug or a feature request for?

For context, I am trying to implement the new Swift 6 features (like sending and @isolated(any) for a library of mine (which does in fact wrap task creation). This post of mine might also provide some context of what I am trying to do: [Is using withoutActuallyEscaping within the context of a TaskGroup valid](Is using `withoutActuallyEscaping` within the context of a `TaskGroup` valid? surcharge)

I also face this issue.
