Get practical maxspeed for openstreetmap

I’m trying to get the practical maxspeed for all ways in a bounding box:

Documentation for maxspeed practical:
https://taginfo.openstreetmap.org/keys/maxspeed%3Apractical#overview
https://wiki.openstreetmap.org/wiki/Key:maxspeed:practical

    res = api.query("""
    way[highway](around:500,52.52,13.40)["maxspeed"]
    ;(._;>;);
    out meta;
    """)

replacing [“maxspeed”] with [“maxspeed:practical”] doesn’t seem to work.
What am I missing?

Works for me - https://overpass-turbo.eu/s/P7m - that query returns the one way that has been tagged with that tag in the search area: https://www.openstreetmap.org/way/68727099/history . If something hasn’t been tagged with maxspeed:practical, then an overpass data won’t return it.

What problem are you trying to solve?
