I didn't know about that wiki site.  If you find a question
that can't be answered easily, could you please forward it
to here?  I think I don't have a time to check that wiki
site that frequently.

Anyway, the `--enable-font-backend' option will disappear as
soon as we can get rid of legacy font-handling codes.
Unfortunately, for Windows and Mac port, we still need them.

By the way, I've just added this note in README.Unicode.

Which font backends to use can be specified by X resource
"FontBackend".  For instance, if you want to use Xft fonts only,

Emacs.FontBackend: xft

will work.  If this resource is not set, Emacs tries to use all font
backends available on your graphic device.

Even if you set it, --enable-font-backend is still necessary
because Emacs calls font-related functions before it checks
above resource.
