While reading through the patch, I stumbled upon this - in the previous
patch, you introduce this code with "pcs-names" and then in this patch
you change the name of the property. I don't think this was mentioned in
the commit message (searching it for "pcs" didn't reveal anything) so
I'm wondering whether this name update should've been merged into the
previous patch instead of this one?
