To paraphrase:
1. Where was the 3.0 change discussed?
2. What was the rationale?

I think these have been answered as well as possible.

3. Can the change be reverted?

It 'could be', but will not be reverted?

4. Should something be added to the doc?

Maybe, but I don't see any enthusiasm from core devs.

This list is for development of future Python and CPython.  The 
continued discussion of what other languages do and how to best use 
rounding are off-topic here (and given the above, on python-ideas). 
Please take these comparison and use discussions to python-list.
