The original release was a proof of concept. That proof of concept is currently being developed into a fully-fledged proposal. Once that proposal is accepted, and legislation is ready, the first actual implementations can begin.

I don't think you can call it a "delay", the project just moves at a glacial pace.

The entire project was never going to finish before 2030. Some banks are upset about it, for sure, but others are in favour.
