Now that you've asked it (and in light of your comment below) I
realize that Rob referred to rewrites of old textual bindings into
YAML schemas, and probably not this patch in particular.

The DTS addition was in the original "merged" series [1]. I will

These are great explainers, thanks a lot for pointing them out!
