I see that a constraint has been introduced so that a label cannot be
repeated inside the same function.

I've already argued on the other thread (5.2 beta-rc1) that I'd prefer a
limit "per-block". There I motivated my preference with an use case for
error management.

I gave up following the other goto thread so I must have missed the "per function" label constraint. It should really be "per block".

Its ashame. The goto syntax isn't easy on the eyes, but it was powerful and allowed a reasonable workaround for standard patterns like continue. But this "per function" limit really blows that; what a pity.
