Why not?  / gets mounted read-only, foreground fsck is run on /, system boots...

Maybe I'm just not understanding the problem here.  I suppose in
theory your root filesystem could be so corrupt that it won't even
mount read-only, but I've never actually seen that happen except in
the case of an outright disk failure.
