Mark other implementations as obsolete

[Solidgol]

First of all, I have been following the goings on since the original announcement on Hacker News, and have really enjoyed following the birth of a new spec.

I recommend marking all the other implementations as implementing a pre-release version of the spec until it has been confirmed that they have implemented the final version.

I think it would be a good idea if you can specify where discussion of extensions to this spec are taking place. It would certainly be interesting to see a consensus for a standard container such as the png container or riff for those wishing to add metadata and other features.

I think it was mentioned somewhere that a video format using this same idea was tested. It would be interesting to have more information about this.

Some discussions are at https://github.com/nigeltao/qoi2-bikeshed/issues and specifically for RIFF, at nigeltao/qoi2-bikeshed#27
