Debian Sid (aka Unstable) is just as bleeding edge as any other "rolling" distro.

[zamadatix]

Sid is a rolling unstable development build, that doesn't compare to a rolling stable release - particularly in regards to conversations on what users should expect.

"rolling stable" is an oxymoron. There cannot be such thing as rolling and stable at the same time.
