I believe you are saying the same things when you are both saying that for this
to work there may be more than one way to do it but all options require
completely new functionality in implementations (either by implementing support
for new labels types or by implementing new fall back behavior). The conclusion
is still the same.

Not true. Binary labels could have been made to work by removing
the left hand label until the remaining suffix consisted of only
RFC 1035 labels, looking up the servers for that domain, then
resuming query processing using those servers similar to what we
do with DS lookups.
Such processing would be required for any new label type used in a
QNAME and would be a significant change to the standard query logic.
