@qcdyx while doing PR #1810 i implemented something like duplicate_geography_id (it was called JsonDuplicateKeyNotice at the time).
I had to remove the code because it was not for 6.0 version.
Here is the commit where I removed the code if it can be useful. Note that since I removed the code the code of interest will be in pink.
commit 67504ab
Some of the code is still there in master, but commented. See GtfsGeoJsonFeaturesContainer.java
