The fontManager is essentially a replacement for what fontconfig provides on many platforms -- so it's intended that the fontManager doesn't exist if the user opts to use fontconfig. However, that's still an "experimental" option because it hasn't been formally tested on many platforms, and, as you point out, there may still be code paths that aren't coded correctly for that option.
