This is still the intention. The current solution is only intended for 
the development stage. The latest HFST runtime library supports flag 
diacritics, but suggestion generation is still in the works.

However, there is an advantage of developing with the full HFST library, 
as it lets all the bells and whistles of the full HFST be used for 
prototyping. When we have a stable set of essential features and 
functions, we will make sure that they are available in the HFST runtime 
library.
