The correct choice depends on how their Emacs has been built; ftcr and
ftcrhb are mutually exclusive [1](see my earlier update to the elisp
manual). I guess we could say something like this:
diff --git a/etc/NEWS b/etc/NEWS
index 6cc392970f..55cf59283c 100644
--- a/etc/NEWS

Note also that 'FontBackend' settings in .Xdefaults or .Xresources, or
'font-backend' frame parameter settings in your init files, may need

+Cairo. Use 'ftcrhb' if your Emacs was built with HarfBuzz support,
+and 'ftcr' otherwise. You can this determine by checking
+'system-configuration-features'. 'x' is still a valid backend.
