This looks great, thanks so much! We could potentially add a link between the validation context docs and the serialization context docs. If users are using one of them, they might want a pointer to the other :).

We'll make sure to get this into the 2.7 release!

Hoping to do a pydantic-core release tomorrow or Tuesday, so we can bump the version + get this across the line :).

@ornariece,

If you could pull in changes from main (which includes a pydantic-core update), this should be ready to merge!

[sydney-runkle]

As soon as this #9064 merges, at least!
