It actually saves me time when writing C, because currently
have to recompile sometimes just to add a pointless
null statements. It is one of the main annoyances
when writing C.

It is also difficult to explain to students
why you can not place a label before a declaration or
at the end of a block while it makes perfect sense
to jump there.

C++ allows placing labels in front of declarations,
so the also improves compatibility.

There is hardly anything to change, as it is entirely
backward compatible and simply removes an annoying
corner case from the language.

In C, there a no corner case anymore. You can place a label
everywhere you could place a statement.
