Hence DNF cannot automatically select the opmtimized subpackage for an installation. That means with current DNF user won't get automatic speedup if the packager decouples the optimized executables into subpackages.
Related to it, I'd like to warn packagers from making the subpackages interchangable from RPM dependency point of view (e.g. all foo-v1, foo-v2, foo-v3 packages providing "foo" dependency symbol and then requiring "foo" from other packages). It would lead to nondeterminism in the initial package installation. -- Petr
