I do think we should be aiming at an ext4 > bitmap-based implementation and an ext3 implementation. Actually, this is a non-issue. The reason that it is handled for extent-only is that this is the only way to allocate space in the filesystem without doing the explicit zeroing. For other filesystems (including ext3 and ext4 with block-mapped files) the filesystem should return an error (e.g. -EOPNOTSUPP) and glibc will do manual zero-filling of the file in userspace.
