Indeed - etags are one example of a server driven mechanism. They need more
machinery than this PR has though. HTTP headers are not always easy to deal
with in client libraries, either access or setting the conditional GET headers.
(And not all developers are aware of or are interested in details (burden) of
all HTTP features.)
POST is the easy way for a client to force a live view. I think we should
leave it in because it is near zero cost.
