Edit: The answer to the title is no. If user wants to use dnfdrake that is a user install. One may install this from OM-Welcome.
Discover and dnfdragora are still on Plasma6 iso. I do not believe these will be removed from repos anytime soon.
The change is that i686 repos were removed from /etc/yum.repos.d. That removes those repos from Discover and dnfdragora,
This is Cooker Plasma 6 x86_64 iso made Feb. 3.
There are 32-bit library packages in our regular repositories. (aarch64, x86_64, and znver1). These have been there since we quit using i686 repos.
The changes to etc/yum.repos.d, Discover, and dnfdragora will appear in next major ROME upgrade and in Rock/6.0.
