We already track the page uptodate status based on the buffer uptodate status, which is updated whenever reading or zeroing blocks. This code has been there since commit a ptool commit in 2002, which claims to: "merge" the 2.4 fsx fix for block size < page size to 2.5. This needed major changes to actually fit. and isn't present in other writepage implementations.
