Sorry, Bob, but after nearly 60 years in the business I can be as cranky as I want. The plain facts are that you can easily add whatever tuner you want as an outboard unit while the majority of users would prefer future development to address issues which can only be accomplished with software updates.
Just use whatever tuner you like, feed it from a selectable output on the board and use the result. No need to waste engineering time on something that is already possible albeit utilizing outboard.
