Key point to avoid any confusion: This is about the RSA-SHA1 cipher combination. It does not mean that RSA is deprecated.
If you use an RSA key for SSH (server or client) you can continue using that.
This should not affect any modern-day SSH implementation, it will only cut off compatibility with SSH implementations not updated for a very long time.
