It may be the best AAC encoder with the source available, but I
disagree that there's no path to merging ours.

I definitely disagree with this. People more commonly use higher bit
rates, and so LC, for stereo AAC audio in video content. SBR is pretty
much needed for multi-channel audio at reasonable bit rates though.
And for music, LC AAC is definitely preferred.
