Yes that would be a lot better and we already support it in jetty.
The issue with the curl usecase using upgrade is that all the upgrade work
is essentially wasted effort - as the bulk upload is done with HTTP/1.1,
you then upgrade to a fully multiplexed HTTP/2 connection, negotiate a
couple of settings, send a single 2xx response and then get a goaway frame
to tear the whole lot down.    What value did the --http2 provide other
than make work!

Failing the direct PRI approach, it would be far better to try the upgrade
on an OPTION request before commencing on the big post/put.

So currently implemented in jetty as an ignore of any h2c upgrade in a
request with a body.

cheers
