Salesforce can make a custom list view visible to a role and its internal subordinates, which is appropriate when the intended audience already aligns with the role hierarchy. Using that audience avoids maintaining dozens of list views against individual users and allows the hierarchy to represent the geographic or organizational population naturally. A queue is intended for supported record ownership and workload distribution, not for governing list-view visibility. Direct sharing to arbitrary individual users is also not the standard list-view model; when the population does not correspond to a role, a public group is typically the better abstraction. The architect must distinguish list-view visibility from record visibility: being able to select a view does not grant access to the Opportunities that satisfy its filter. Each user still sees only records allowed by object permissions, OWD, hierarchy, sharing rules, teams, and other record-level mechanisms.
