Here's what I do:
from rosidl_runtime_py import get_interface_path
from rosidl_adapter.parser import parse_message_file
m = parse_message_file('std_msgs', get_interface_path('std_msgs/msg/Bool'))
it's actually better than what you do with RosPack as parse_message_file parses the lines for you and returns a nice object with all the info in it.
Right now, you can use the public API for ros2 msg, which can locate the file for you:
https://github.com/ros2/ros2cli/blob/...
But then you'll need to open the file and read the contents for yourself.
Additionally, there should be a Python API which will parse the file for you and give you a Python object representation of it, part of rosidl_adapter.parser:
