The problem is that addressing it is very non-trivial, we've had a rough design for what we want to do for about a decade (look for some of Lars-Peter's ELC presentations for some summaries) but what we're missing is someone with the required combination of time and enthusiasm to actually implement it. A lot of the refactorings that Morimoto-san has been doing which move everything to be a component rather than distinct CODEC, CPU or platform types has been preparatory to the main refactoring.
