The license issue is with AACS, required for replicated BD but not for BD-R(W). If one is authoring BD for replication, that fee must be paid; for BD-R, no fee is needed, which is what allows Toast and the new FCS to burn BD-R.
It sure would be nice for Apple to a least fix DVD SP to allow the menus created with the extant system for DVD to be converted to BD-R menus. No, that doesn't live up to the full potential of BD, but it's a "northward" move for us serious hobbyists.
I suspect the other issue with provided full BD menu design software, is that BD menu creation, the Java, et al, is an order of magnitude more complex in design than BD. Apple is no doubt trying to design a system that allows access to more features, but still keep it wysiwyg and fairly simple.
For pros authorize serious contents for replication, access to a more complete set of BD features is needed. I think the licensing should be handled like mpeg-2 decoding in Quicktime: you pay extra for a special key that unlocks the ability to write the AACS files. The price of that license is determined by Sony et al, not by Apple. But at least one could get it.
The question for Apple is whether or not it is worth the investment: will serious professionals use DVD/BD Studio vx to author BD for replication, and if so, are there enough of them to justify the software design and implementation expense?
BD Playback: licensing is not a serious issue: BD hardware players (set top, Playstation, etc.) are not that expensive any more, and the add-ons you must buy to play BD on Windoze are cheap enough.
