I cannot see any causal relationship between "widely deployed"
and "enormous cost"; the cost would surely be much the same
were there just a handful of users, would it not ?

On the other hand, the number of parsers is small and finite;
how many input method editors are there for all the world's
natural languaqes, I wonder ?  That is surely where the real
cost would lie, were we to adopt Henri's preferred solution.
