please either stick to the ldh set and the issue of the validity of any string composed from this generating set, or explain why, other than for rhetorical excess, you are permitted to pick an arbitrary point in the us-ascii standard and wave it about as proof of some claim.
there exist rules, much earlier than 1123, about "-" as the initial, or terminal, byte in a sequence of bytes, and about sequences of two or more instances of "-" where neither byte is the initial, or terminal, byte in a sequence of bytes.
there exist rules, much earlier than 1123, about any digit as the initial byte in a sequence of bytes.
there exist rules, much earlier than 1123, about whether a sequence of bytes must contain more than one byte.
it is my understanding that a view associated with liman's draft is that some protocol restriction existed in fact, or should be generously imputed to have existed as a protocol restriction in the minds of some implementers, and that one or more of these rules are not completely explained as allocation policies by historic allocators of some zone of interest.
i don't share that view, and i don't think it prudent to abandon whatever merits may support that view by appealing to the absence of us-ascii values outside the ldh set, or phrasing like "old timey".
