get_usermeta() deprecated in favor of get_user_meta(). But why doesn’t it make use of it?

While coding WP I just wondered about this simple fact:

get_usermeta() is deprecated since version 3.0. The warning suggests me to use get_user_meta(). Even the parameters are pretty similar, I wonder why the deprecated function is not making use of the new function as well.

Isn’t that a sign that the new function does not really does what the deprecated did?

I’m wondering because I need to replace deprecated calls and wonder a bit.

What makes me even wondering more is the simple fact that get_user_meta() is quite an alias of the 2.9 function get_metadata() with only a constant value’ed parameter ‘user’ given.

Help 😉

Edit: A counter-example is clean_url() – it’s deprecated, the error message shows what this is about and the deprecated function aliases the new one: esc_url(), so it’s clear what to do.
