Quite possibly true.

Every change potentially breaks something. (How would you have changed
1/2 from 0 to .5 without breaking anything?) The issue is cost versus
gain. We do maintenance bugfix releases because the gain for bugfixes,
and the gain of applying them immediately, is *usually* considered
greater than the cost. Some bugfixes are delayed to the 'next' version.
Non-bugfix changes require deprecation for at least one version before
making the change.
