Hm, one more question, why wasn't this picked up by the tests:

kueue/test/e2e/singlecluster/fair_sharing_test.go

Line 121 in 1d849aa

g.Expect(cq2.Status.FairSharing.WeightedShare).Should(gomega.Equal(int64(0)))

?

[alculquicondor]

Because that doesn't check the yaml. It checks the go types, which should parse empty as zero.
