Comment # 3 on bug 960082 from Andreas Stieger

This feature first appeared in OpenSSL 1.0.2. Downgrading to
feature/enhancement.

Apache httpd 2.4.17+ is not in openSUSE Leap 42.1, so it's not a bug within the
distribution, only when upgrading to unsupported packages.

On the maintenance submission SR#350514 :

openSUSE:Leap:42.1:Update/openssl is inherited from SUSE:SLE-12-SP1:Update. If
that is to remain the case, this backport must go through SLE maintenance, and
even the SLE feature process as it adds functionality. Otherwise we need to
split the package.

Recommend we save this for SLE 12 SP2 and openSUSE Leap 42.1, and users wishing
to run mod_http2 from development packages update their openssl version to
match.

Unless there is comment to the contrary I am going to reject this proposed
update.
