app.oam.dev/component label length

Discussed in #6471

I have created a component that can have a user submitted name input. Sometimes it can be longer than 63 characters and I cannot block it because it is a requirement by the user.

K8s labels must not be more than 63 characters, so here is my problem:

cannot create object: custom.component "rxpy29mfqh20vblfweylcw-assume-there-is-a-super-long-name-with-over-63-characters-long-0" invalid:
metadata.labels: Invalid value: "assume-there-is-a-super-long-name-with-over-63-characters-long-0": must not be more than 63 characters

When I examined a successfully created component, I saw that the following values were created:

labels
 ...
 app.oam.dev/cluster: local
 app.oam.dev/component: component-name
 app.oam.dev/name: xxx
 app.oam.dev/namespace: project-xxx
 workload.oam.dev/type: custom-component
 ...

I noticed that the name of the custom component is written as app.oam.dev/component. It fails with the above error message because it is more than the allowed length.

cue:

"custom-component": {
	type:        "component"
	description: "..."
	labels: {}
	annotations: {}
	attributes: {}
}

template: {
	output: {
		apiVersion: "example.com/v1alpha1"
		kind:       "MyKind"
		metadata: {
			name: parameter.clusterID + "-" + context.name
		}
		spec: {
			props: {
				name:       context.name
				clusterID:  parameter.clusterID
			}
		}
	}
	parameter: {
		clusterID: string
	}
}

input:

context:
  name: assume-there-is-a-super-long-name-with-over-63-characters-long-0
  namespace: project-test
parameter:
  clusterID: rxpy29mfqh20vblfweylcw

Can you please direct me to what might be possible to resolve this issue?

Thanks in advance!
