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.
