I can understand a configuration that says "We take only atomics
when a push tries to update more than one", but this one is iffy.

If the receiver accepts non-atomic from older send-pack, those with
newer send-pack should have a way to say "the receiving end may
prefer atomic, but I choose not to."  Is there a way to do so?

And if there is such a way, what value does the preference add to
the user experience and the server's operation?
