## New (274)

- Ambiguous overlap in intent. `includes` returns `Globs` for a scope, while `get_filtered_globs` returns `FilteredGlobs` and takes `custom_excludes`. It is unclear if `includes` is a simplified version of `get_filtered_globs` with no custom excludes, or if they serve distinct filtering logic. The naming convention (`includes` vs `get_filtered_globs`) is inconsistent.
