In the i686 discussion in #Fedora we currently hear quite a lot of voices in support for the Steam client, but not that much of other use cases.
If you have anything specific using i686 packages on Fedora, which is _not_ Steam, this is a good time to mention it, so that your use cases are not lost.

And please do not panic, it is a discussion, nothing is decided yet :)
