Thanks, applied both patches, but for this part:

I did not like the idea of not storing RSNXE in some cases and instead,
addressed this corner case in the actual validation step. This is not
really something that is supposed to ever happen in real production use
cases (i.e., SAE would be used instead of there is support for RSNXE),
but anyway, I guess this is convenient to have available for testing
purposes.
