Federico, I share your frustration. Many patches get stale.
It is difficult to remember all the bits and pieces of design choices
discussed during a 13-month review process.
And also to maintain a patch always up-to-date for one year, also
considering that it is not very motivating as obviously not many people are
interested ...
Also many patches are now overlapping, block each other or similar, and it
is difficult decide which one to prefer for a reviewer.
There are many features in the queue that might be interesting to unlock.
I have the feeling this project is slowly losing interest.
