I fear the cairo port is at least a year away

So it's not a solution to our next releases

Can you patch fontconfig so apps get OTF (OpenType CFF) versions by
default, unless they explicitely request OpenType TTF files? (when the
same version of the same font is available in both formats)

That would simplify the problem to just having OO.o use the second mode
till it fixes its bugs (plus probably just hide any CFF font to apps
using the second mode)

I must admit my main motivation for split packaging was avoiding the QA
hell of some users getting TTF in OO.o, others getting OTF, having OO.o
fail, and open bug reports.
