Just checked the mkfs.ext4 man page and no, that doesn't seem to be the case. This was about five years ago so the precise question I can't perfectly remember, but the nature of it was as stated; It was a question about a specific filesystem setting default value, on a specific version of a specific distribution of linux, inode size, bytes per inode or bytes per block. Apologies for sounding a little addled but it's been five years since I have been a systems administrator so it's all melted together in my memory.
