Hello

You are right, this is more an answer for the first 2 patches. We are
generally okay with adding a new line to 'show protocols all' from the
compatibility point of view. But our rule of thumb here is that we do
not want to add a line here that is purely configuration data without
a good reason, as this command should mainly show runtime data.

People could argue that half of BGP configuration options are important
enough to be shown here and we would like to avoid adding them all,
especially when these command outputs are manually implemented.
