that's not quite correct. It's rather than there was no need so far for
existing implementations to have parameters on decode, this was never a
limitation of the design, see e.g. the comments below:

/* AAC modes are required for encoders and decoders */

* IEC modes are mandatory for decoders. Format autodetection
* will only happen on the DSP side with mode 0. The PCM mode should
* not be used, the PCM codec should be used instead.
