The issue doesn't seem any different - assuming you have concurrent requests, you also have to make sure the cache doesn't return a result until the whole document is written to it.

That's a fair point - I didn't consider that issue, because using a standard HTTP cache, that's taken care of.

It's just become somebody else's problem (the developers of the HTTP cache), but it's fair to say it's still an issue to solve.
