plugin to handle openapi custom properties

[jux61]

Hello,
I need to develop a plugin to handle custom properties in my openapi contracts.
For example i have a custom property to handle item writable only on create operation (x-createOnly) or on update operation (x-updateOnly).
I want x-createOnly items to be displayed in model/example only for a POST body, and x-updateOnly for PUT body.
I target only openapi 3.1 schema.
I'm able to handle my custom properties for the model wrapping function fn.jsonSchema202012.getProperties and using a custom context to know in which context function is called (get, post, put).
To handle it for examples, i thought to wrap fn.jsonSchema202012.getSampleSchema to modify my schema before generate the example, but i'm not able to use hook in this function to know the context.
Do i miss something or is there a better solution to handle my case?

I succeed to do something, not very pretty, but it's work...
I use a statePlugins action to set my context in parameters component,
I wrap function getSampleSchema to get the context using a statePlugins selector and add readOnly flag in schema for property i want to ignore in that context

i'm opened to a better idea if someone has :)
