It's not that it's triggered rebuilds, but that it's triggered builds.
It's also triggered builds on powerpc64le and riscv64. Before any
package which had openblas as a transitive dependency wasn't built by
the CI because it wasn't substitutable¹. People still have the option of
using package transformations to use openblas tuned for the cortex a7 or
a15 on armhf, but in reality this just unlocks substitutes for those
~5600 packages which wasn't available before.
¹ We saw this in the past briefly in the past when openzfs made its way
as a dependency to qemu and through that to Gnome.
