yes, location of message_filter make it a challenging case for migration. As you said, split it out from ros_comm and into a small repo require significant effort, so you prefer to separate a branch/fork on ros_comm, right? In new branch, I try make message_filter support both ros version with some conditional code?

I don't think this is a good path forward. Simply because significant parts of the repo would be irrelevant for ROS 2 which would make synchronizing the diverging branches more and more effort.

how I handle other packages, keep them intact?

I don't have a good general recommendation for you at the moment.
