Debian stable was just one example, why it is important that the TYPO3 
core team sticks to the deprecation rules.

Having a new major version that allows breaking changes does not mean 
you are forced to break things by all means. And it definitely does not 
mean you should break your own rules.

And if the change is breaking a behaviour that has been recommended 
until 4.7 (i.e. how to implement a hook) this should still be announced 
early and then has to wait until the deprecation phase is over.

We had a similar problem after the user experience week in 2009, when 
everybody was eager to get in as much ExtJSified things as possible, 
without taking care of performance and functionality. Now it seems to be 
about Extbasified things, namespacing and what is called "clean code" 
with similar results.

Don't get me wrong, I can clearly see the advantages of these changes, 
but still they should be implemented more carefully and with the real 
world use cases of our target group in mind. And this target group 
simply does not care about clean code or namespacing, when this means, 
that major functionality is now missing, broken or considerably slower 
than before.
