Eventually yes. However, that's something that will take a lot of work. 
When similar common APIs were introduced into Linux, there was a 
transition period of 1-2 years where new code was immediately written to 
the new APIs, and old code (e.g. legacy clock API implementation, and 
its callers) was slowly converted. I would expect the same thing in 
U-Boot; any other approach means preventing new work until the 
conversions are complete, which would be rather stagnating.
