The endterm attribute is mainly useful when the toolchain does not support automatic link target text generation for a particular situation. In the past, this was required by the man page tools for all reference page links, but that is no longer the case, and it now actually gets in the way of proper automatic link text generation. The only remaining use cases are currently xrefs to refsects.
