shouldn't we also check the global and current scope?

[szokeasaurusrex]

It should not be necessary. User should always only be set on the isolation scope:

sentry-python/sentry_sdk/api.py

Lines 332 to 334 in 747f0f3

	def set_user(value):
	# type: (Optional[Dict[str, Any]]) -> None
	return get_isolation_scope().set_user(value)

I checked the (few) places we manually call set_user on a scope, these also use the isolation scope only.
