Yes, the RIFF INFO chunk is added to the file, but the file format itself does not support that. It's not a wave file anymore, it's something else with a PCM stream.

That is not true. wav, as any RIFF based format, is extensible by its nature. Adding different chunks to it will not make it any less of a wav file. Specifically for RIFF INFO chunk, it is the standard metadata format for RIFF based formats and it is defined in the original Multimedia Programming Interface and Data Specifications that defines the Waveform Audio File Format. The specifications even includes an example of a PCM WAVE file with an INFO chunk:

RIFF( 'WAVE' INFO(INAM("O Canada"Z))
fmt(1, 1, 44100, 132300, 3, 20)
data( <wave-data> ) )

The only trouble with this metadata is that it's hardly supported by applications. (this wav tag editor and Windows Media Player 12 are two examples of the few programs that do support it)
