I know this feature is intended to make it easier for people to compile wine, but people who aren't comfortable with this should use precompiled packages.
I don't agree with this. For most software, I will use an RPM, but I refuse to use Wine RPMs. Either it is not optimized for my setup, or weird things happen (like I can't run anything unless I'm root.) Wine-install makes installing Wine simple and painless, and if you want to make and compile yourself w/o wine-install, you can do that too. So, there's no harm in keeping it around.
