The FastAPI instrumentation accepts an 'explicit_urls' argument on initialization. This commit translates that concept to the Flask instrumentation.

Does _before_request and _rewrapped_app need the excluded_urls passed in as well?

Good catch.
I need to extend test_automatic.py to cover this case and then I'll push up the change.

GitHub didn't update the comment since the change is a few lines up, but this should be taken care of now on line 220 in this commit:

The Flask instrumentation can be applied on two levels: * The `module` level (auto-instrumentation), which patches the `Flask` class. * The `app` level, which patches a `Flask` instance. This commit applies a few missing `excluded_urls` keyword arguments to ensure the auto-instrumentation provides the same configurability as the app-level instrumentation.
