I think static ::get('foo') and ::set('foo', 'bar') methods are acceptable
compromises, but get() really shouldn't replace getInstance(). It
provides a Singleton instance. The standard way of telling that to the
user is with the name "getInstance()". New users who are uncomfortable
with this terminology can stick to Zend_Registry::get('foo') and
Zend_Registry::set('foo', 'bar').

I should hope developing a web application is not equivalent to driving a
car, otherwise we're all out of jobs.
USING a web application is equivalent to driving a car. In that case, I
agree, the user should only be familiar with the basic concepts (using a
mouse and keyboard, navigating the web, using a browser). It takes no
specialized expertise to fill out a form. You don't have to be a
Formula-1 driver to get to the grocery store.
On the other hand, developing a web application is equivalent to building
a car from scratch. Zend Framework simply provides the engine, wheels,
and drive train to help you do it. You still should know how to put the
thing together. Frankly, if you're not familiar with how brakes work,
everyone is better off if you never leave the garage. :-)
