Reproduction for #7346.

_experiments={"data_collection": None} type checks, but the two functions reading the option disagree about what None means:

• has_data_collection_enabled() (sentry_sdk/utils.py:2108) gates on key presence → True
• _resolve_data_collection() (sentry_sdk/data_collection.py:287) only treats a non-None value as user provided → provided_by_user=False

So the client lands between the two: every caller of has_data_collection_enabled() takes the data collection branch, while the resolved config is the legacy send_default_pii=False mapping. None is the only config where the two disagree — sentry-python/7346/repro.py prints that gate table first, then the three observable symptoms:

1. the default EventScrubber is skipped, so extra["password"] is sent as hunter2
2. WSGI request attributes gain http.query, url.path and url.full
3. an explicitly configured event_scrubber is discarded, with a warning claiming data collection configuration was provided

Running it

cd sentry-python/7346
uv run repro.py

No DSN needed — events are inspected in before_send. It runs against this checkout, since data_collection is an unreleased _experiments option, and exits 0 while the bug reproduces, 1 once it is fixed.

One correction to the issue

The issue's table reports [Filtered] for data_collection={}. On master that config also yields hunter2, because skipping the EventScrubber is intended whenever data collection is configured (sentry_sdk/client.py:357). The report still holds — the divergence is has_data_collection_enabled() vs provided_by_user.

I closed this because I was trying to create a reproduction locally and the bot decided to go off on its own...
