I believe the behavior described here is due to this:
https://www.reddit.com/r/emacs/comments/1b69v1b/let_magit_330_use_builtin_transient/

To summarize, the user has a built-in version of transient.el 
shipped with Emacs 29.2.
They installed magit 3.3.0, which requires transient 0.3.6. 
Instead of package.el seeing magit's transient.el dependency as 
satisfied by the built-in version, it installed the latest 
version.

I've patched Elpaca, which relies on package--builtin-vesrions, 
due to similar complaints about transient.el being pulled in 
despite the built-in version satisfying a dependency.
