There is one complication: It turns out that in newer versions of apache2, mod_http2 does no longer support being used with mpm_prefork but only with mpm_worker and mpm_event. If loaded together with mpm_prefork, mod_http2 will log a message and refuse to serve HTTP/2, but HTTP/1.x continues to work. As I don't see any other way to fix the open issues, I would still like to go ahead. But I will prepare a new package/diff with a NEWS.Debian entry that informs about this change. Cheers, Stefan
