Cool Options for replacing subfloor on pier and beam

My 1965 ranch home needs the subfloor replaced in several areas. Problem is that the original subfloor is compose of 1/2" plywood upon which are build the interior walls of the house.

The contractor is proposing to block up the interior walls as shown and then cut away all of the 1/2" plywood except the plywood under the interior walls (shown in light blue in the Proposed image attachment). Finally, they would butt new OSB up to the walls and glue and screw it to the floor joists

I like this approach because it is cost effective and easier than bracing all of the walls in order to replace the 1/2" plywood, but I worry about what will happen when the 1/2" remnants ultimately deteriorate.

Do you like this approach or would you do it differently?

All ideas are welcome. Thanks!

Yes that is the correct way to do it.

What's the real issue your having?
Is it with the flooring bouncing or the walls?
Why would the 1/2" plywood deteriorate?
There has to be more to this story.

It won't be too hard to replace the plywood under the bottom plate if that's what you want him to do. It's basically just a shim at this point.
