We'll also need to update our go.mod / go.work files to go 1.26.0, which will bring in a crop of required govet fixes around Eventf calls

We likely want to make those vet fixes and take them back to release branches so they are ready for go 1.26 as well

Can you add a comment or spot to track the changes / release branch minor bumps as well, like #3957 (comment) ?

[dims]

When we move stable branches to 1.26, we will have to apply this as well: kubernetes/kubernetes#137451

Either that same SHA of google.golang.org/protobuf documented there or a newer tag! otherwise the file sizes of our binaries will explode!

PS: also see kubernetes/kubernetes#137408
