A few things in Pkg rely on inference to figure out (empty) collection types and error if inference can't figure it because the subsequent method signatures are narrow.
I wouldn't really care for any other package, but when working on inference it's not uncommon for it to temporarily be somewhat broken. It's useful to still have Pkg available so that the build finishes and that it is possible to install extra packages for debugging.
