Well, that's why I stated it the way I did.  Making some minor API
changes between 1.0 and 2.0 is expected, but if a developer has to learn
a completely new API and change every line of his code that uses ZF,
that would not be good.

Another form of preserving backward-compatibility is to create implement
new classes and methods that coexist with old ones, without affecting
apps that use the old code. That's why you see methods like
mysqli_real_escape_string() or execute2().  I really dislike seeing
things like that, but they are sometimes necessary to preserve backward
compatibility.

So, in short -- yes, seriously, backward-compatibility is important.
Zend Framework will achieve more success and more IT departments will
use it, if and only if the project shows some commitment to keeping API
contracts.
