it won't be "legacy" any more in the course of the 2nd
step and RIPE's 2-yr holding period comes into play (=> it can't be transferred
during that time).
Note also there's voices recommending not to sign an RSA for legacy space (in
certain situations, at least),
router discovery gets broken by too tight of filters.

specific deployments of NPTv6 like stuff for connections to supplier/partner
networks (to map those to their own address space) but these are corner cases
not even relevant for their "firewalls".

om what I understand, in their scenario RAs are not sent to link-local
scope all nodes (ff02::1), so that would eliminate another attack vector
(depending on the actual processing of RAs on the CPEs).
