Did Google effectively just take their own stab at WML and WAP? I remember using a flip phone around 2002 with that awesome technology to view sports scores.
Google still has their WAP transformation tool ("Google Wireless Transcoder"):
edit:
It looks like Google more recently rolled out another tool (googleweblight.com) for shrinking web pages. This does not generate WAP, however.
It's really just a library that uses (polyfilled) Custom Elements. The only unusual thing is the auto-CDNing.
