/**
 * When set implementation cannot be resolved by ID, we try to avoid failing graph building
 * for now instead, we will leave this loose end unresolved. There are a few different cases
 * where this could happen:
 *
 * 1. In Pure, we used to let users define property mappings with source/target set implementation
 *    pointing at another class mapping from a different mapping, which might not be available in
 *    the included mapping hierarchy and it would still work, see the following issues for more details:
 *    See https://github.com/finos/legend-studio/issues/880
 *    See https://github.com/finos/legend-studio/issues/941
 * 2. When we handle unknown mapping include, since the mapping include is unknown, we might not be
 *    able to resolve the underlying mapping and its children class mappings, so like case (1), some
 *    source/target set implementation might not be resolvable.
 *    See https://github.com/finos/legend-studio/pull/2242
 *
 * While (1) is definitely an anti-pattern, (2) is a fairly valid use case in order for us to properly
 * support unsupported
 * See https://github.com/finos/legend-studio/issues/315
