On i386 I'm not surprised, the BIOS does understand the MBR layout (at least
on some systems) so expects sector zero of hard disks to contain one...

Not worth it, you are starting to dig a hole...
If nothing else the filesystem is likely to be inaccessibly to anything
else booted on that system.

Of course floppy disks (unless they are ls120s) do not contian an mbr.
