I was working on the ImageCollection reduceRegions method for geetools. When building stuff i usually work in a notebook using eerepr it's pure bliss as i dont' need to run getInfo() all the time.

I was looking at the following dataset from your documentation:

## Import the example feature collection and drop the data property.
ecoregions = (
    ee.FeatureCollection("projects/google/charts_feature_example")
    .select(["label", "value", "warm"])
)
ecoregions

And I got the following:

{'type': 'Feature',
 'geometry': {'type': 'Polygon',
  'coordinates': [[[-109.20999998777032, 31.420000027612016],
    [-108.3000000221122, 31.41999998395071],
    [-108.3000000221122, 32.029999957333146],
    [-109.20999998777032, 32.03000002411591],
    [-109.20999998777032, 31.420000027612016]]]},
 'id': '00000000000000000000',
 'properties': {'label': 'Desert', 'value': 0, 'warm': 1}}

The method only returns 3 properties: ["label", "value", "warm"]

Problem

Now using the same dataset, explore the available properties in the first feature:

ecoregion.first().propertyNames()

["system:index", "label", "value", "warm"]

The consequence is that everything relying on the getInfo() method becomes misleading:

• the code editor
• the eerepr method: https://github.com/aazuspan/eerepr/issues/42
• the geojson

side effect

If I manually set up a "fake" system property like system:image_id then it will also be discarded in the getInfo() which makes me think that you actually implemented my request from https://issuetracker.google.com/issues/329235200 without telling it to the user. That makes it inconsistent with the other objects (Image, FeatureCollection, ImageCollection).

Is there any plan to align them ?
