I did make such changes and thought them to be correct, but had not tested them at all. You are the guinea pig, and it appears that you lived! If you did things like native builds without your filesystem going down in flames, then it is probably not too likely to go down in flames due to the new changes. The new ext2fs format changes are not really much change from the perspective of the kernel/filesystem (a little more for e2fsck). The new mke2fs doesn't turn on the dir_prealloc_blocks feature, so you have not exercised that part of the changed code. Probably the only thing exercised is the sparse_super support, and that is really nothing but ext2fs not going out of its way to check and complain about something.
