We normally don't look at which reverse dependencies are enabled to
enable features in a dependent package. We do the opposite: look at
which of our dependencies are available to enable features.

What is the size increase of enabling this option? If it is
significant, we want to introduce a BR2_PACKAGE_LIBYANG_LYD_PRIV
sub-option, and select it from the frr package.

Thanks!

Thomas
