This begs several questions that would probably need to be clarified e.g. in
the packaging guidelines. For example:
------
I am adding a brand new package to multiple Fedora releases. The package is not
noarch. It successfully builds on i686. What am I supposed to do?
a) build it on i686, until it fails there
b) excludearch %ix86 right away not to create a dead dep tree
c) excludearch %ix86 on F37+ only, as this is a F37 change
-------
I am updating a package that no longer builds on i686. How do I know if I can
exclude it safely? What checks do I run? Am I allowed to push this update to
stable Fedora releases?
-------
My package is noarch but has multiple arched dependencies. How do I properly
make Koji not attempt to build it on i686?
Extra question:
Do I need to add Obsoletes of the i686 package(s) to the x86_64 one(s)?
a) always
b) only when XYZ
c) never
