Ok I can think of one myself. It's a problem in other projects too.
Having them separate makes it easier to run a newer ftview (say, with a new feature), against older freetype / multiple versions of freetype for comparison. That, however, would work find if like other projects one could run "make install" within src/. With FreeType's currently build system it's an all-or-nothing. So, we'd need to revamp the build system a bit before the merge can happen.
