-    // also we could pass directly an instrumentation for add/replace
-    // PROS:
-    // - no need to rewrite all instrumentations
-    // - all options are possible (add, remove, replace)
-    // - no messing with OTel config types, we're extending
-    // CONS:
-    // - typos coud lead to unexpected behaviors (double instrumentation)
-    // - `instrumentationName` may be not unique???
-    // OTHER OPTIONS:
-    // - use `instrumentations` and have a `mode` property
-    //    - mode extend to add new classes and replace
-    //    - mode replace to completelly rewrite instrumentations
-    //
-    // CRAZY IDEA:
-    // have a mode to include only the instrumentations of the detected packages
-    // for performance gains
-    // - method should be recursive to check all app dependencies
-    //    - it would require to scan all instrumentations to extract the modules they patch
-    // - or we could have a map per instrumentation name
-    //   - eg. 'mongoose' => ['@opentelemetry/instrumentation-mongoose', '@opentelemetry/instrumentation-mongodb']
-    // - would require to use a function similar to `safeGetPackageVersion`
-    //   - using `module-details-from-path`
