Again, the cynical voice...
It's a nice idea - write things once and run them anywhere.
Trouble is:
- The vendors need their lock-in. AWS don't want customers to migrate to Google, neither want them to migrate to Azure. There's not many places to go after that.
- You don't want to build your exciting new product with its competitive features at the behest of a competitor, let alone some other self-assigned arbiter. It would have an incredible chilling effect.
It's a nice pipe dream, but won't work in reality.
That's not to say it's impossible in a limited extent - HTML was universal enough to give us the World Wide Web, for example.
