The text from the standard says:
The posix_fallocate() function shall ensure that any required storage for regular file data starting at offset and continuing for len bytes is allocated on the file system storage media. If posix_fallocate() returns successfully, subsequent writes to the specified file data shall not fail due to the lack of free space on the file system storage media.
I stand by my assertion that it is currently impossible to provide this with Thin Provisioning without actually writing to every single block.
