• [nitpick] Function name 'is_packaged_installed' is unclear; consider renaming to 'is_package_installed' for grammatical correctness and clarity.

def is_packaged_installed(package_name):

src/serviceconnector-passwordless/azext_serviceconnector_passwordless/_utils.py:143

• Add unit tests for 'is_packaged_installed' to cover both installed and not-installed scenarios and validate error logging paths.

def is_packaged_installed(package_name):

src/serviceconnector-passwordless/HISTORY.rst:7

• [nitpick] The changelog entry for version 3.3.4 is too vague; consider detailing specific improvements and fixes to help users understand what changed.

* Some improvements and issue fixes.

[Copilot]

Instead of using 'import' to check package installation, consider using 'importlib.util.find_spec' to avoid executing package code for a simple presence check.

Suggested change

	__import__(package_name)
	return True
	except ImportError:
	return False
	from importlib.util import find_spec
	return find_spec(package_name) is not None
