Now we can happily read and process the request body in both rewrite
and access phase handlers in nginx 0.8.54+. And ngx_lua is already
doing that for both the lua_need_request_body config directive and the
"ngx.req.read_body()" Lua API.

No, I think we're talking about making ngx_upload easier to work with
other nginx modules, especially with those registering a content
handler like ngx_lua, ngx_echo, ngx_proxy, and ngx_fastcgi.

The whole point here is to make ngx_upload read and process the
request body in an earlier phase like "rewrite" and "access" phases,
such that we can preserve the content handler for other modules and
can eliminate internal redirects altogether to reduce runtime cost.

Sorry for the confusions in my previous emails :)
