Just my two cents, but I've had way more trouble with missing packages. It's a pity, but Ubuntu repositories are growing at a much faster pace.

If I want the latest and greatest I can always compile from source...

Just to add to your comment. I've had almost zero issues with Sid, and the issues I've had I've avoided by using apt-listbugs anyways. I can't say that when I tired Ubuntu and Mint. Mint actually botched my install on an update, took me 3 hours to undo the mess and I promptly backed up and installed Debian on that machine. YMMV
