I think I know now why I was confused by your point on isatap not
allowing more than a single host. It is not strictly the case that nodes
on an isatap link must use isatap addresses as the source/destination
addresses in packets. If there is a way for the isatap router to discover
host routes, then  nodes on the isatap link can use , e.g., RFC 3041
privacy addresses.

In other words, the only addresses that need to be in isatap format are
those that appear in the next-hop fields of a node's IPv6 routing table
entries. (In many cases, those next-hop addresses could simply be link-
local.) As such, a single isatap client can connect many additional hosts.
