HI all!

Can I ask why 'define-package' was marked obsolete?
I can not find any information about it. I have searched the log,
where I could only find the respective commit
<https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=ade7a212a882540178d9504e7e0bd3be3bf1fd41>
.

I have also searched the Emacs news for versions 28, 29 and 30,
but also there, I can find no information.

Also in the comments of package.el itself I can not find any information
about it.

Is it documented anywhere?

Thanks!
