I'm removing my linoleum and laying a piece of Luan over the old piece of Luan with peel and stick tile over that. The old underlayment has become week in spots and I can see where the linoleum is stretching in the low spots....
The floor should not become weak, sag or have any low spots. Putting down an additional layer of luan will not fix the problem. You need to determine the reason for the deterioration and fix it. I would be especially concerned about water intrusion.
Regarding the original question, that gimping is decorative without any structural purpose.
The floor is structural foam attached to aluminum framing. The structural foam has pretty much given out in spots where the aluminum framing was too wide. I saw this when I removed the bottom cover to search for my electrical short and had to clean up the crumbled Styrofoam. It was a poor design and I have seen others doing the same job to similar units over on LOA when I was a member.
I'm actually thinking about covering up the whole thing and not removing anything, it would only raise the floor 3/8 of an inch and only affect 1 piece of trim. Definitely going to take the easy way out for this one.
