Wrong. I keep close watch on what packages I have installed. I only have
32bit wine installed at the moment, so your statement seems untrue:
$ rpm -qa wine\* |grep i686 |wc -l

I never said anything about cross-bitness requirements. You
misunderstood. And I've just demonstrated that dnf doesn't always pull
in 64bit package when 32bit counterpart is being installed.
