Pros:

I don't know enough about RPM packaging or DNF CoW to say either way, but I
wonder if these enhancements might also contribute to getting DNF CoW's
"reusable extents" feature working? If I understood the FOSDEM presentation
correctly, DNF CoW would not only save the installer from having to rewrite
the file to the user's disk on update when the file has not changed, it
would also not download the file in the first place if it hasn't changed.
Presumably this depends on the same functionality that deltarpm would need
to identify unchanged files in RPM packages? So if these enhancements to
deltarpm would also contribute to DNF CoW, I would consider that another
plus.
Here is the DNF CoW FOSDEM presentation if anyone is interested in it.

Just my two cents.
