Correct, another way of looking at it is from a programming angle. If Debian fixes a bug that breaks your tool, then Debian is unstable. Therefore, to maintain stability, Debian must not fix bugs unless they threaten security.

The term "stable" is the most polluted term in Linux, it's not something to be proud of. Similar to how high uptime was a virtue, now it just means your system probably has been pwned at some point.
