Yes and no. The only intent of the review on dsd@acpica.org to catch
functional/non-compliance issues with the property. The vendor needs to
own it and ensure the support is added in the kernel before shipping it.

Honestly nothing. But the agreement was vendor needs to proactively get
it reviewed and add the support. The community can reject if it has
functional/compliance issues.
There has been elaborate discussions in the past on this and I provided
the link to the final agreement on that. It's always better to avoid
using them as first option if possible, else get the review/agreement
that it's good to use property.
