Good, then lets work all together and get the best of it.

Your series has good features like the update of the command line addons 
without rebuild, including updating of the signature when applicable. 
However your series still has weaknesses it had in previous versions. I 
was hopping we could work all together to improve it, but you have been 
repeatedly telling that my proposal doesn't fit your needs without 
explaining why. Can we work in a more win-win spirit this time ?

By the way, for the record, here is a link to a series I sent out as an 
exemple of what it could look like. The intention at that time was not 
to have a concurrent series, but just to show what I meant in my 
comments, because exemples are often more explicit than words. That 
series was considered more mature and closer to a mergeable state than 
yours at that time. Link to the said series: 
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?state=*&series=237158

Your series only converts a few architectures, and I can't see any 
demonstration that it will be possible to convert other architectures as 
a follow-up without too much pain.

This is not an argument. Billions of computers are running Micr*s*ft 
Windows, does it make Windows better ? Do IBM or Google claim about the 
million equipment they are sending out with special Linux features ? 
Showing objectively what's the benefit of your features without 
referring to Cisco would be better.
