What about

Suggested change

AdditionalProxyConfigRef *corev1.LocalObjectReference `json:"additionalProxyConfigRef,omitempty"`

UnsafeHAProxyConfigTemplateRef *corev1.LocalObjectReference `json:"additionalProxyConfigRef,omitempty"`

So we are explicity about "use at your own risk"; also, dropped additional according to latest discussion in the issue (it should be replace)

Not sure i like the use of Unsafe as that sounds scary 💀 Could we use something like CustomHAProxyConfigTemplateRef or CustomLoadBalancerConfigRef

Re-raising this as i think it got lost.

Not sure i like the use of Unsafe as that sounds scary 💀 Could we use something like CustomHAProxyConfigTemplateRef or CustomLoadBalancerConfigRef ?

I don't have a strong opinion here, not sure what other think

No big opinions on my side either :-) I think the unsafe comes from:

Let's [...] make sure to clearly document the contract about it: e.g. no validation, use at your own risk, etc.

[0]

There are a number of areas where there is no/little validation, and you can do lots of damage. For example PreKubeadmCommands.

If we have a warning in the documentation of the field that states "you better know what you are doing" then that's probably enough.

I agree with Richard. I think we don't need Unsafe in the field name

There are so many ways to misconfigure Cluster API easily in which it's totally impossible for us to validate. I think it's not necessary to additional communicate it here by adding an Unsafe prefix to the field.
