Hi, I had suggested that change to make sure that the installed wine package works flawlessly in any respect with winetricks. First off, this isn't fail-proof either, because this is a "or" dpendency (e.g. you might install a recent wine-development next to an ancient and problematic wine package).
However imo none of the issues in older Debian wine(-development) packages were critical, and there are known workarounds for them. Basically we would need an unversioned "Depends" on wine(-development), and a versioned "Recommends". Given this, and that the version constraints are met anyway in Debian stretch/sid, it wouldn't do us harm to remove them again. Sorry for the short-sighted advice, Joseph. As benefit of removing the constraints again, users might e.g. install winetricks on jessie (if we'd go for offical jessie-backports we might restore some of the just dropped documentation in there).
