Redwood Defaulting and Validation on Promote and Change Position Page

We see that, currently, Promote and Change Position flow is not on the list of supported Pages to utilize the feature of Defaulting and Validation in redwood via Visual Builder.

https://docs.oracle.com/en/cloud/saas/human-resources/fauvb/guidelines-for-implementing-defaulting-and-validation-rules.html

Since Defaulting and Validation is available for "Change Assignment", "Promote" as well as "Request a Position Change" flow, which are essentially mirroring the same functionality as "Promote and Change Position", can we expect that Defaulting and Validation is actually working and is supported? Also given the fact, the Validation and Defaulting features are actually enabled on the page.
