It's things like this that put me off of Samsung ROM's...
I am not defending Sammy ROMs, but every ROM has it's issues. Name them - RB, CM, RR, NR, WL, PA, etc. The way development works these days is to produce something because the masses wants it and then wait for the masses to come back with bug reports so it can be fixed. RR and CM develops as time goes by - they bring out nightlys and often these are ridden with bugs. Then someone comes up with a bugfix and you have to flash it in order to get a stable feature. This fix gets implemented and released i na later version, but in the meanwhile you are stuck with the problem.
When you say "things like this", you must remember that there is no official JB rom out yet. It is a leaked rom. Leaked roms are prone to issues and the risk to the end user is higher than when official roms/fw is released by Samsung (similar to nightlys). The difference is that CM, RR and the rest don't care for bugs, because it is all still under development and the bugs will be sorted out in due course. I love these roms, but then just when they perected the GB version, ICS is introduced. Then Development on ICS starts and just when that is perfected, JB comes out and so the cycle continues.
But when Samsung officially releases a rom/fw, there are little to no bugs. I remember the ICS leaked rom/fw LPB (correct me if I am wrong). The rom was so buggy, I uninstalled it faster than the installation. I could not live with the crap that was leaked. The subsequent roms/fw was almost bug free compared to the leaked version.
In the same vein, you should be put off by most custom roms out there. I am not attacking you, I just thing that your preference is with another developer because they try to implement features that Sammy roms never included before. I loved RR and CM, but there were small niggly things that kept me from using it as daily drivers for long periods. I always reverted to stock because of small things that were not implemented in the custom roms at the time. Now with JB, Samsung has taken so much from CM, RR and the like while still keeping the features that kept me using official fw. I doubt I will flash another custom rom as a daily driver if the official releases are going to be the same as the leaked version (but with bug fixes).
