I think these didn't get much attention so far since the resulting 
files are not really playable. Implementing WAVFORMATEx along with 
these would probably be more attractive to developers.

It's submitter role to ask for review. IRC is often the place to do so. 
A convincing argument often includes the use cases for your changes. In 
this case:

"Wrong channel mask should be ignored" Question remain on why, and what 
would it mean if you want to playback this stream ?

"As long as we don't support WAVFORMATEx wavenc should accept more than 
2
channels and just ignore the mapping." Question remain on why not 
implementing WAVFORMATEx, and what would be the recommend way to guess 
the channel layout (if <= 18 channels) to make the stream somewhat 
playable.

By gstreamer you mean wav support. I'm sure you won't waste your time. 
Adding new standard format is always welcome. If something in the core 
need to be extended, this list is the place to make the proposition.

cheers,
