So, not necessary but often a good idea. It's correct that, once built and running, a FreeBSD system never needs = /usr/src. However, a -STABLE or -CURRENT FreeBSD system will need = /usr/src to apply any security advisories or errata (as happened = recently, re: OpenSSL). Unlike -RELEASE branches, -STABLE and -CURRENT = don't get updates via freebsd-update. Also, it's handy to have /usr/src and rebuild if ever there is a feature = MFC'd that you'd like to have available on your -STABLE system (e.g., = the bhyve support for AMD processors that was MFC'd not so long ago). = That's usually the main reason for running -STABLE, actually.
