Describe the solution you'd like
This should be possible

Http.collectManaged[Request] {
 case GET -> !! / "users" => ZManaged.succeed(Response.ok)
}

I think I may be able to take this one, I have something that appears to work but I'm fairly new to the ZIO world. If I can take this one my first question is going to be: Is it appropriate to call useNow on the ZManaged to get a ZIO here?

I forgot to link to this issue with my PR but I believe this is closed with #909
