Deciding what platform my output will finally be delivered on has become a pain for me too. I've ended up for the handful of clients I've worked for in getting a truly, drilled-through agreement as to what format I have to supply. I then sign off only according to what has been agreed.
As you have found getting a universal LEVELS format nowadays is impossible. The only thing I can advise is make a strict policy as to on what device and player your output can be played and provide as many levels versions as to make you and your collaborators happy.
