I checked again and nope, not tag, but Rob's question was legitimate and I reworded
and clarified the commit message following your reviews.
On the other side you suggested a Fixes tag, which I added.

The rewording is about why reg doesn't make sense on the nature of the memory
region and it doesn't make sense here like other similar nodes.
