There is no inevitability - on the contrary, there is a very low
probability. But I agree with the conclusion, since I don't think
either kind of ULA has any business in the global DNS.
But we appear to be on last call with a document that recommends
all flavours of ULA can have PTR records in the global DNS.
(and the collision probability for locally assigned ULA's PTR records
is the birthday probability, which exceeds 0.5 for 1.24 million entries.)
i.e. at least for the local assigned ULAs global DNS PTRs appears to
me to be something you don;t want to put in the global DNS.
