I'd love to report more stuff in Wine but isn't there a requirement to be running the latest/dev branch? This is tricky to do in Debian (because I prefer to build debs of whatever and then install those).
You will be asked to test it in the latest release, yes, but perhaps someone else can test it for you, or at least get developer eyes on the issue. In any case, it's unlikely to be just closed invalid without any consideration. We would rather know about it than not.
