No, becaaue it is not reliable, see commit:
c6bca8cef fs/ext2: Remove support for auto-calculation of rootfs size
In the end, it does nto make sense to do auto-calculation, because on an
embedded device, you have to now the layout and size of your storage.
So, you know what size you want your ext filesystem to be.
