We must go forward and not back.
Just to conclude the original question on this thread: 'defer_recdef' is unused, untested, unmaintained. So it falls under the normal garbage-collection of source code. I will remove it next week or so, unless there is another strong argument to keep it.
In contrast, the main 'recdef' is maintained a bit longer; of course without any plans to "localize" it. Asymptotically, 'function' should take over its role, but there is presently no attempt to change the situation.
