e.g.:

Implementation considerations

We should evaluate where the effort matters and where it doesn't.

Research direction

Start by reviewing the linked pull requests, rclcpp/pull/1119 and rclcpp/pull/1056, to understand which backports were blocked by ABI changes. Then identify where ABI stability matters in rclcpp and document the areas worth addressing. Done means the scope and an implementation approach are agreed, since the issue currently asks for evaluation rather than naming a concrete change.
