While I generally disable deltarpm locally, you need to look at teh
whole picture. There are many parts of the world that generally have
caps on downloads. Australia is an example of such a country, using
deltarpms there can save you a ton of bandwidth that goes against your
download cap. now some ISP's run mirrors and if you hit their mirror it
doesnt count against your cap. but thats not always a given.  The sane
default is what we have today.

in the initial use case laid out that started this thread the user
should be using ansible or puppet or something for config management.
and then it is a trivial thing to disable deltarpm.
