It should be obvious that a file that offers content also has allocated blocks. Blocks are "allocated" when the OS decides whether the new data will fit on the medium. The fact that some filesystems may have data in a cache but not yet on the medium does not matter here. This is how UNIX worked since st_block has been introduced nearly 40 years ago. A new filesystem cannot introduce new rules just because people believe it would save time.
