Upstream removes support for SSH-1 protocol and we plan to do the same
in Fedora. The protocol is years obsolete and not even supported in
current default binaries (only in openssh-clients-ssh1 subpackage).

== Detailed Description ==
SSH-1 protocol was introduced more than 20 years ago and is no longer
considered secure. OpenSSH package in Fedora is built without SSH-1
protocol since 2015 (SSH-1 clients are available in
openssh-clients-ssh1 subpackage). OpenSSH upstream plans to remove the
code completely in next release, which prevents us from using this
technique further and remove the support completely (unless there will
be significant demand for compat package).

== Scope ==
* Proposal owners:
Remove subpackage openssh-clients-ssh1 and potentially create
compat-openssh-clients-7.5 package with clients supporting SSH-1
protocol.
