Because they'll go away.

Why?

Because it's clutter. And because there should preferrably be only one 
way to do things. If we left all the old ways around indefinitely, we'd 
have code that uses two or more ways of doing the same thing all over 
the place. It would set bad examples, to begin with.

Theuni was recently very confused about the difference between three 
different APIs that do exactly the same thing (registering a utility). 
If we had deprecated at least the most confusing one of them (ztapi) 
already, it would probably have been much clearer.
