-> Stability: 0 - Deprecated: Use subpath patterns instead.
-
-Before subpath patterns were supported, a trailing `"/"` suffix was used to
-support folder mappings:
-
-```json
-{
-  "exports": {
-    "./features/": "./features/"
-  }
-}
-```
-
-_This feature will be removed in a future release._
-
-Instead, use direct [subpath patterns][]:
-
-```json
-{
-  "exports": {
-    "./features/*": "./features/*.js"
-  }
-}
-```
-
-The benefit of patterns over folder exports is that packages can always be
-imported by consumers without subpath file extensions being necessary.
