Due to #1721, colinhacks/zod#2860 (comment), and #1719 I'm exploring the possibility to alter the behaviour of `.brand()` for storing the `brand` property as a way to distinguish the proprietary schemas in runtime. This can replace the `proprietary()` function with a call of `.brand()`. However, so far it turned out to be breaking because `ZodBranded` does not expose the methods of the wrapped schema, such as `.extend()`, which is used in `accept-raw.ts` endpoint for possible route params. —— After a series of serious considerations I realized that exposing brand to consumers of `express-zod-api` could be a beneficial feature. Runtime brand can be accessed via `._def[Symbol.for("express-zod-api")].brand`
