Why 'define-package' marked obsolete?

[dalanicolai]

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.

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!
