There has never been a restriction on consecutive hyphens, otherwise they
would not have been usable in IDN A-labels.
"have only letters or digits or hyphen as interior characters."
from 921
now had there actually been a protocol restriction on sequences of
hyphen longer than one, (years before any implementation of the
protocol) then your observation would be correct, and we'd have to use
some other mechanism to signal "interpret as" to some layer above.
