Routing based on ALPN

I'm looking for a way to route traffic on port 443 based on ALPN value
without SSL termination.
ssl_preread_module  does something similar but the only exposed
variable ($ssl_preread_server_name) is for SNI, not ALPN.
A bit of context. I'd like to use nginx to host regular HTTPS server on port
443 but if the ALPN value is 'xmpp-client' transparently proxy the traffic
to my local Jabber server. This feature  is already supported by several
Is there a way to access and save ALPN value to a variable?
Thank you for your time.
