As a longtime LaTeX user, I find this behavior irritating, not once has it saved me effort. I would much rather have LaTeX exit to shell immediately and to report a good error. Instead, the dynamic "fix" is applied in opaque manner, totally unclear what the compiler did, it optimizes for "patch the input so compilation runs to completion" instead of "do what the user wanted", and once LaTex has finished, the user still must manually edit the original file to get a proper solution.
