Well, that would change the looks of our default DejaVu fonts a lot.
(freetype-freeworld currently disables the BCI for the DejaVu family by
default for that reason, which has always been a controversial move, I'll of
course stop doing that from F13 on.) I'm not convinced this is a good idea
to ship as an update.

If you need subpixel antialiasing, no. I will continue to build freetype-
freeworld packages for the subpixel stuff.

"It" as in subpixel rendering? There have been patches to Cairo to use the
FreeType subpixel filters, they even remove some probably patent-encumbered
code (dumb subpixel filters) from Cairo itself, but still they haven't been
accepted yet. :-(
As FreeType always provides the relevant APIs, just implemented as dummies
which always return an error, it's perfectly possible to make the decision
whether to use freetype-freeworld's subpixel filters at runtime (e.g. Qt 4
As for the BCI, it should need no special support from Cairo nor Pango.
