My ultimate choice of using Debian was heavily influenced by the non-rigid release cycle.
I would hope that the Debian team doesn’t fall into the trap of forcing new functionality into the stable release before it had been properly tested, as some GNU+Linux distributions seem to have done, repeatedly, in the past.

However, this change doesn’t really affect me too much, as my home desktop systems are running under the testing/unstable branches of Debian. I am, however, concerned about the possibility this may affect the stability of the stable branch on the servers I run, as well as my wife’s Debian installs (she stick with the stable branch).
