The draft has the following:
The "internal" top-level domain provides this purpose in the DNS. Such
domains will not resolve in the global DNS, but can be configured within
closed networks as the network operator sees fit.

I think that is the difference between .internal and 10.in-addr.arpa. I
expect 10.in-addr.arpa. to resolve in the global DNS. RFC-1918 address do
leak and there is no reason to expect every piece of software to have
filter in place to catch reverse DNS lookups for those addresses.

There seems to be an argument that for the convenience of DNSSEC, private
domains have to resolve in the global DNS. Maybe we need to actually
say that in some RFC. Or solve this issue in a different way.
