Mostly about effectivity vs. efficiency in terms of game programming.
If this works that simple by default. I should be able to flash my firmware and try some other, better-suited compilers for it. I hope they all also provide a way to upload it. Otherwise I could also imagine writing only one program at a time, always overwriting the default NXT firmware. But well, also only if there are libraries to make use of it. I don't exactly. However, I can, in all cases, use NBC/NXC for programming with the default firmware bytecode. I'd still like to get a GCC toolchain working for it.
