There is harm borne by the unwilling client receiver: battery and data allowance are not free.

Yup, I understand that part. :)
I'm doing a poor job of pointing out that any harm done by doing something like this is borne by the party doing it.
... so why mandate it-- if there turns out to be a positive benefit of doing such a push in the future, fine.
I guess I'm attempting to argue that, unless we can figure out how this causes harm/is likely to be done accidentally and cause issues, then it is better to not say anything about it. Saying something about it creates a spec with is more fragile.

I'm not suggesting that this is Osama's motivation, but look at the
Upgrade scenario: the server is the first to send on the HTTP/2.0
session with a response.  There's an obvious opportunity there to push
prior to the client SETTINGS frame arriving.  The TLS scenario is less
interesting - the client sends SETTINGS prior to any request, making
defaults non-interesting.
