] So I cant imagine a case where a simple   "select * from package where
] package_id in (package1_id, package2_id, package3_id)"  will not suffice to
] emulate a join with no performance issues.

Except where (package1_id, packate2_id, ...) is long. There will
be a point where it is more efficient to do the join in the other
direction, e.g. "select 10 most recently modified packages and
join with other data from redis or whatever".
