Custom context with superRefine

[oof2win2]

Hey there, is there a possibility of adding a custom context (say with a this or some other parameter) to a .superRefine addition? I need to use an external variable that I cannot get during the superRefine run, so I need to have something like this:

const allIDs = [1, 3, 6]
const schema = z.object({
  id: z.number()
})
  .superRefine((data, ctx) => {
    if (!allIDs.includes(data.id)) ctx.addIssue...
})

Would it however be possible to have something like this instead? It allows for the functions to be pure and be ran in cases where you obtain the data some way (such as by a database query or an API call) to allow for the schema to have only validation code, rather than also including code to fetch the data itself.

const schema = z.object({
  id: z.number()
})
  .superRefine((data, ctx, params) => {
    const {allIDs} = params
    if (!allIDs.includes(data.id)) ctx.addIssue...
})

I was also wondering if this is possible. Injecting contextual runtime data (without fetching it all the time from the server via .refine(async val => ...)) seems like a nice feature. Is there something like this planned? I'd like to help out implementing it.

It would be great if this could be done even higher up at the chain, at the parse level: schema.parse(data, context), such that we could use the context in transform or overwrite as well as refinements, but without it ending up in the result data. In my particular case, I am using zod schemas to add derived properties to objects. I can simply add a _context property, but that creates other issues/limitations.
