The list would still allow a many-to-many relationship. Let demonstrate:
entity A and entity B both have 2 members: A-1, A-2, B-1, and B-2.
we add a "relations" field to entity A, which is a list of IDs from B, describing the list of B's that A is related to.
A-1 has the relations field as:
[B-1, B-2]and A-2 has[B-1, B-2].As you can see, this is a many-to-many relationship. Each of our entities is tied to multiple entities. So this is many on both sides, hence many to many
That's overly complicated to my eyes, and not really relevant. The point I was trying to make is just that a join table is unnecessary in the situation you originally described.
What I described in the comment above is the same thing I originally described, but expanded.
A dependency relation can still be many to many (and in my case, it is). The comment above gives an example to prove it.
