I really like the idea of being able to style the fallback text to minimise reflow.
I don’t agree with the notion of changing a browsers default behaviour though.
Whether FOUT is acceptable or not should not be decided by the designer, but by the user. Some users might find it very disturbing, while others might need it because downloading large fonts over a slow connection would make their browsing too slow otherwise.
Therefore it is a good thing that browsers behave differently, although preferably all browsers should have a setting to let the user control the behaviour.
