Well, I can't imagine there being a use for the L/R system in new
construction. It would be only in a repair. And if that is the case, you'd
just take it apart at the "accessible" union, and take apart backwards to
the problem area.

The term "accessible" has a slightly different use in building. Anything
is accessible with the right hammer, but normally, hidden joint between
walls, under floors, etc cannot be joined with a union. It may be
accessible during construction, but not after the room is finished.
