Will this break HA clusters during upgrades? Not all masters are updated simultaneously: #51049 (comment)

I think this is slightly different usecase than what you're pointing to. There, the issue is about upgrading from beta1 to beta2, where both are enabled by default. Here, we are migrating from alpha to beta, iow. from non-default to a default enabled API.
If I don't change controller to use the beta (enabled by default) cronjobs will not be working. Because you'll have the beta API available, but controller will rely on non-default API to be turned on.
This will break HA clusters, but only those that explicitly enable the alpha version. I'll defer to @bgrant0607 or @smarterclayton for the decision but imho this should get in.

We don't support HA alpha upgrading to beta without interruption. So someone on a cluster like that has already broken the glass.
