For platform features that directly affect web developers' pages that might
sometimes be true. However, compression is also optional in HTTP and it
doesn't appear to have caused problems or made some sites work and others
not based on some dominant implementation.

There is still discussion in the IETF about whether stream or frame based
compression is best. That's the right place to have that discussion. There
are also implementers that want extensions for other things, such as
multiplexing. This is a protocol layer handshake below the API and the API
simply provides information about what was agreed.
