Is it possible to have multi-key discriminators?

Do you want to request a feature or report a bug?

Feature

What is the current behavior?

Currently, we can only have one key as the discriminator key, but as discussed in #5846 (I think it was closed by accident) it seems like a nice feature

What is the expected behavior?

The possibility to use multiple keys as discriminators to track "sub-versions" of a discriminator. It's kind of related to #2851 since it would allow the use of multiples discriminators on the same document

Are there any plans for implementing this in the future?

No plans currently, but this is an interesting idea. We will consider it for a future release.
